The API is documented in the public header files of the GNU +Objective-C runtime: +</p> +<ul> +<li> <samp>objc/objc.h</samp>: this is the basic Objective-C header file, +defining the basic Objective-C types such as <code>id</code>, <code>Class</code> +and <code>BOOL</code>. You have to include this header to do almost +anything with Objective-C. + +</li><li> <samp>objc/runtime.h</samp>: this header declares most of the public runtime +API functions allowing you to inspect and manipulate the Objective-C +runtime data structures. These functions are fairly standardized +across Objective-C runtimes and are almost identical to the Apple/NeXT +Objective-C runtime ones. It does not declare functions in some +specialized areas (constructing and forwarding message invocations, +threading) which are in the other headers below. You have to include +<samp>objc/objc.h</samp> and <samp>objc/runtime.h</samp> to use any of the +functions, such as <code>class_getName()</code>, declared in +<samp>objc/runtime.h</samp>. + +</li><li> <samp>objc/message.h</samp>: this header declares public functions used to +construct, deconstruct and forward message invocations. Because +messaging is done in quite a different way on different runtimes, +functions in this header are specific to the GNU Objective-C runtime +implementation. + +</li><li> <samp>objc/objc-exception.h</samp>: this header declares some public +functions related to Objective-C exceptions. For example functions in +this header allow you to throw an Objective-C exception from plain +C/C++ code. + +</li><li> <samp>objc/objc-sync.h</samp>: this header declares some public functions +related to the Objective-C <code>@synchronized()</code> syntax, allowing +you to emulate an Objective-C <code>@synchronized()</code> block in plain +C/C++ code. + +</li><li> <samp>objc/thr.h</samp>: this header declares a public runtime API threading +layer that is only provided by the GNU Objective-C runtime. It +declares functions such as <code>objc_mutex_lock()</code>, which provide a +platform-independent set of threading functions. + +</li></ul> + +<p>The header files contain detailed documentation for each function in +the GNU Objective-C runtime API. +</p> +<hr> +<div class="header"> +<p> +Next: <a href="Traditional-GNU-Objective_002dC-runtime-API.html#Traditional-GNU-Objective_002dC-runtime-API" accesskey="n" rel="next">Traditional GNU Objective-C runtime API</a>, Up: <a href="GNU-Objective_002dC-runtime-API.html#GNU-Objective_002dC-runtime-API" accesskey="u" rel="up">GNU Objective-C runtime API</a> [<a href="index.html#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="Indices.html#Indices" title="Index" rel="index">Index</a>]</p> +</div> + + + +</body> +</html> |
