gcc: GNU Objective-C runtime API

1 8.1 GNU Objective-C Runtime API
1 ===============================
1
1 This section is specific for the GNU Objective-C runtime. If you are
1 using a different runtime, you can skip it.
1
1 The GNU Objective-C runtime provides an API that allows you to interact
1 with the Objective-C runtime system, querying the live runtime
1 structures and even manipulating them. This allows you for example to
1 inspect and navigate classes, methods and protocols; to define new
1 classes or new methods, and even to modify existing classes or
1 protocols.
1
1 If you are using a "Foundation" library such as GNUstep-Base, this
1 library will provide you with a rich set of functionality to do most of
1 the inspection tasks, and you probably will only need direct access to
1 the GNU Objective-C runtime API to define new classes or methods.
