C functions have an arbitrary number of arguments and one return value. Each function is thus - uniquely identified by the function name and the set of C types which describe the function arguments - and return value. The global variables exported by the API are similarly identified by their name and - their type. - </p> -<p> - A C API is thus merely defined by a set of names to which a set of types are associated. If you know the - function calling convention and the mapping of the C types to the machine types used by the platform you - are on, you can resolve the name of each function to find where the code associated to this function - is located in memory, and then construct a valid argument list for the function. Finally, all you have to - do is trigger a call to the target C function with the argument list. - </p> -<p> - For the sake of discussion, here is a sample C function and the associated 32 bit x86 - assembly code generated by GCC on my Linux box: -</p> -<pre class="programlisting"> -static void function_foo (int foo) -{} - -int main (int argc, char *argv[]) -{ - - function_foo (10); - - return 0; -} - -push $0xa -call 0x80482f4 <function_foo> -</pre> -<p> - The assembly code shown above is pretty straightforward: the first instruction pushes - the hexadecimal value 0xa (decimal value 10) as a 32-bit integer on the stack and calls - <code class="function">function_foo</code>. As you can see, C function calls are implemented by - gcc by native function calls (this is probably the fastest implementation possible). - </p> -<p> - Now, let's say we want to call the C function <code class="function">function_foo</code> from - a Python program. To do this, the Python interpreter needs to: - </p> -<div class="itemizedlist"><ul class="itemizedlist" type="disc"> -<li class="listitem"><p>Find where the function is located.

A dynamic type system allows you - to get information about every instantiated object at runtime. It can be implemented - by a process-specific database: every new object created registers the characteristics - of its associated type in the type system. It can also be implemented by introspection - interfaces.

During compilation of C code, the compiler maps these - language types to the compiler's target architecture machine types. If you are using a C interpreter - (I have never seen one myself but it is possible :), the interpreter (the program which interprets - the source code and executes it) maps the language types to the machine types of the target machine at - runtime, during the program execution (or just before execution if it uses a Just In Time compiler engine). - </p> -<p> - Perl and Python are interpreted languages which do not really provide type definitions similar - to those used by C.

It -will generally comprise a function of some kind and a marshaller -used to call it. It is the reponsibility of the marshaller to -convert the arguments for the invocation from <a class="link" href="gobject-Generic-values.html#GValue" title="GValue"><span class="type">GValue</span></a>s into -a suitable form, perform the callback on the converted arguments, -and transform the return value back into a <a class="link" href="gobject-Generic-values.html#GValue" title="GValue"><span class="type">GValue</span></a>. -</p> -<p> -In the case of C programs, a closure usually just holds a pointer -to a function and maybe a data argument, and the marshaller -converts between <a class="link" href="gobject-Generic-values.html#GValue" title="GValue"><span class="type">GValue</span></a> and native C types. The GObject -library provides the <a class="link" href="gobject-Closures.html#GCClosure" title="struct GCClosure"><span class="type">GCClosure</span></a> type for this purpose. Bindings for -other languages need marshallers which convert between <a class="link" href="gobject-Generic-values.html#GValue" title="GValue"><span class="type">GValue</span></a>s and suitable representations in the runtime of the language in -order to use functions written in that languages as callbacks. -</p> -<p> -Within GObject, closures play an important role in the -implementation of signals. When a signal is registered, the -<em class="parameter"><code>c_marshaller</code></em> argument to <a class="link" href="gobject-Signals.html#g-signal-new" title="g_signal_new ()"><code class="function">g_signal_new()</code></a> specifies the default C -marshaller for any closure which is connected to this -signal. GObject provides a number of C marshallers for this -purpose, see the g_cclosure_marshal_*() functions. Additional C -marshallers can be generated with the <a href="glib-genmarshal.html">glib-genmarshal</a> utility. Closures -can be explicitly connected to signals with -<a class="link" href="gobject-Signals.html#g-signal-connect-closure" title="g_signal_connect_closure ()"><code class="function">g_signal_connect_closure()</code></a>, but it usually more convenient to let -GObject create a closure automatically by using one of the -g_signal_connect_*() functions which take a callback function/user -data pair. -</p> -<p> -Using closures has a number of important advantages over a simple -callback function/data pointer combination: -</p> -<div class="itemizedlist"><ul class="itemizedlist" type="disc"> -<li class="listitem"><p> -Closures allow the callee to get the types of the callback parameters, -which means that language bindings don't have to write individual glue -for each callback type. -</p></li> -<li class="listitem"><p> -The reference counting of <a class="link" href="gobject-Closures.html#GClosure" title="struct GClosure"><span class="type">GClosure</span></a> makes it easy to handle reentrancy -right; if a callback is removed while it is being invoked, the closure -and its parameters won't be freed until the invocation finishes. -</p></li> -<li class="listitem"><p> -<a class="link" href="gobject-Closures.html#g-closure-invalidate" title="g_closure_invalidate ()"><code class="function">g_closure_invalidate()</code></a> and invalidation notifiers allow callbacks to be -automatically removed when the objects they point to go away. -</p></li> -</ul></div> -<p> -</p> -</div> -<div class="refsect1"> -<a name="gobject-Closures.details"></a><h2>Details</h2> -<div class="refsect2"> -<a name="G-CLOSURE-NEEDS-MARSHAL:CAPS"></a><h3>G_CLOSURE_NEEDS_MARSHAL()</h3> -<pre class="programlisting">#define G_CLOSURE_NEEDS_MARSHAL(closure) (((GClosure*) (closure))->marshal == NULL) -</pre> -<p> -Check if the closure still needs a marshaller.

It provides the -facilities for registering and managing all fundamental data types, -user-defined object and interface types. Before using any GType -or GObject functions, <a class="link" href="gobject-Type-Information.html#g-type-init" title="g_type_init ()"><code class="function">g_type_init()</code></a> must be called to initialize the -type system. -</p> -<p> -For type creation and registration purposes, all types fall into one of -two categories: static or dynamic. Static types are never loaded or -unloaded at run-time as dynamic types may be. Static types are created -with <a class="link" href="gobject-Type-Information.html#g-type-register-static" title="g_type_register_static ()"><code class="function">g_type_register_static()</code></a> that gets type specific information passed -in via a <a class="link" href="gobject-Type-Information.html#GTypeInfo" title="struct GTypeInfo"><span class="type">GTypeInfo</span></a> structure. -Dynamic types are created with <a class="link" href="gobject-Type-Information.html#g-type-register-dynamic" title="g_type_register_dynamic ()"><code class="function">g_type_register_dynamic()</code></a> which takes a -<a class="link" href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> structure instead. The remaining type information (the -<a class="link" href="gobject-Type-Information.html#GTypeInfo" title="struct GTypeInfo"><span class="type">GTypeInfo</span></a> structure) is retrieved during runtime through <a class="link" href="GTypePlugin.html" title="GTypePlugin"><span class="type">GTypePlugin</span></a> -and the g_type_plugin_*() API. -These registration functions are usually called only once from a -function whose only purpose is to return the type identifier for a -specific class. Once the type (or class or interface) is registered, -it may be instantiated, inherited, or implemented depending on exactly -what sort of type it is. -There is also a third registration function for registering fundamental -types called <a class="link" href="gobject-Type-Information.html#g-type-register-fundamental" title="g_type_register_fundamental ()"><code class="function">g_type_register_fundamental()</code></a> which requires both a <a class="link" href="gobject-Type-Information.html#GTypeInfo" title="struct GTypeInfo"><span class="type">GTypeInfo</span></a> -structure and a <a class="link" href="gobject-Type-Information.html#GTypeFundamentalInfo" title="struct GTypeFundamentalInfo"><span class="type">GTypeFundamentalInfo</span></a> structure but it is seldom used -since most fundamental types are predefined rather than user-defined. -</p> -<p> -Type instance and class structs are limited to a total of 64 KiB, -including all parent types. Similarly, type instances' private data -(as created by <a class="link" href="gobject-Type-Information.html#g-type-class-add-private" title="g_type_class_add_private ()"><code class="function">g_type_class_add_private()</code></a>) are limited to a total of -64 KiB. If a type instance needs a large static buffer, allocate it -separately (typically by using <a href="./../glib/glib/glib-Arrays.html#GArray"><span class="type">GArray</span></a> or <a href="./../glib/glib/glib-Pointer-Arrays.html#GPtrArray"><span class="type">GPtrArray</span></a>) and put a pointer -to the buffer in the structure. -</p> -<p> -A final word about type names. -Such an identifier needs to be at least three characters long. There is no -upper length limit. The first character needs to be a letter (a-z or A-Z) -or an underscore '_'.

I guess this means that - all praise and all curses will be directly forwarded to him. - </p> -<p> - GObject's memory management model was designed to be easily integrated in existing code - using garbage collection. This is why the destruction process is split in two phases: - the first phase, executed in the dispose handler is supposed to release all references - to other member objects. The second phase, executed by the finalize handler is supposed - to complete the object's destruction process. Object methods should be able to run - without program error (that is, without segfault :) in-between the two phases. - </p> -<p> - This two-step destruction process is very useful to break reference counting cycles. - While the detection of the cycles is up to the external code, once the cycles have been - detected, the external code can invoke <code class="function"><a class="link" href="gobject-The-Base-Object-Type.html#g-object-run-dispose" title="g_object_run_dispose ()">g_object_run_dispose</a></code> which - will indeed break any existing cycles since it will run the dispose handler associated - to the object and thus release all references to other objects. - </p> -<p> - Attentive readers might now have understood one of the rules about the dispose handler - we stated a bit sooner: the dispose handler can be invoked multiple times. Let's say we - have a reference count cycle: object A references B which itself references object A. - Let's say we have detected the cycle and we want to destroy the two objects. One way to - do this would be to invoke <code class="function"><a class="link" href="gobject-The-Base-Object-Type.html#g-object-run-dispose" title="g_object_run_dispose ()">g_object_run_dispose</a></code> on one of the - objects. - </p> -<p> - If object A releases all its references to all objects, this means it releases its - reference to object B. If object B was not owned by anyone else, this is its last - reference count which means this last unref runs B's dispose handler which, in turn, - releases B's reference on object A. If this is A's last reference count, this last - unref runs A's dispose handler which is running for the second time before - A's finalize handler is invoked ! - </p> -<p> - The above example, which might seem a bit contrived can really happen if your - GObject's are being handled by language bindings. I would thus suggest the rules stated above - for object destruction are closely followed. Otherwise, <span class="emphasis"><em>Bad Bad Things</em></span> - will happen. - </p> -</div> -</div> -<div class="footer"> -<hr> - Generated by GTK-Doc V1.18</div> -</body> -</html>

Then, the instance size and instantiation - policy (if the n_preallocs field is set to a non-zero value, the type system allocates - the object's instance structures in chunks rather than mallocing for every instance) - declared by the user are used to get a buffer to hold the object's instance - structure. - </p> -<p> - If this is the first instance of the object ever created, the type system must create a class structure. - It allocates a buffer to hold the object's class structure and initializes it. The first part of the - class structure (ie: the embedded parent class structure) is initialized by copying the contents from - the class structure of the parent class. The rest of class structure is initialized to zero. If there - is no parent, the entire class structure is initialized to zero. The type system then invokes the - base_class_initialization functions (<a class="link" href="gobject-Type-Information.html#GBaseInitFunc" title="GBaseInitFunc ()"><span class="type">GBaseInitFunc</span></a>) from topmost - fundamental object to bottom-most most derived object. The object's class_init - (<a class="link" href="gobject-Type-Information.html#GClassInitFunc" title="GClassInitFunc ()"><span class="type">GClassInitFunc</span></a>) function is invoked afterwards to complete - initialization of the class structure. - Finally, the object's interfaces are initialized (we will discuss interface initialization - in more detail later). - </p> -<p> - Once the type system has a pointer to an initialized class structure, it sets the object's - instance class pointer to the object's class structure and invokes the object's - instance_init (<a class="link" href="gobject-Type-Information.html#GInstanceInitFunc" title="GInstanceInitFunc ()"><span class="type">GInstanceInitFunc</span></a>)functions, from top-most fundamental - type to bottom-most most derived type. - </p> -<p> - Object instance destruction through <code class="function"><a class="link" href="gobject-Type-Information.html#g-type-free-instance" title="g_type_free_instance ()">g_type_free_instance</a></code> is very simple: - the instance structure is returned to the instance pool if there is one and if this was the - last living instance of the object, the class is destroyed. - </p> -<p> - Class destruction (the concept of destruction is sometimes partly - referred to as finalization in GType) is the symmetric process of - the initialization: interfaces are destroyed first. - Then, the most derived - class_finalize (<a class="link" href="gobject-Type-Information.html#GClassFinalizeFunc" title="GClassFinalizeFunc ()"><span class="type">GClassFinalizeFunc</span></a>) function is invoked. The - base_class_finalize (<a class="link" href="gobject-Type-Information.html#GBaseFinalizeFunc" title="GBaseFinalizeFunc ()"><span class="type">GBaseFinalizeFunc</span></a>) functions are - Finally invoked from bottom-most most-derived type to top-most fundamental type and - the class structure is freed. - </p> -<p> - As many readers have now understood it, the base initialization/finalization process is - very similar to the C++ constructor/destructor paradigm. The practical details are different - though and it is important not to get confused by superficial similarities. - GTypes have no instance destruction mechanism. It is - the user's responsibility to implement correct destruction semantics on top - of the existing GType code. (this is what GObject does.
