Attaches a GLX context to a window or GLX pixmap.
OpenGL C bindings library: libGL.a
Bool glXMakeCurrent(Display *dpy GLXDrawable Drawable GLXContext Context)
The glXMakeCurrent subroutine does two things: (1) it makes the specified Context parameter the current GLX rendering context of the calling thread, replacing the previously current context if one exists, and (2) it attaches Context to a GLX drawable (either a window or GLX pixmap). As a result of these two actions, subsequent OpenGL rendering calls use Context as a rendering context to modify the Drawable GLX drawable. Since the glXMakeCurrent subroutine always replaces the current rendering context with the specified Context, there can be only one current context per thread.
Pending commands to the previous context, if any, are flushed before it is released.
The first time Context is made current to any thread, its viewport is set to the full size of Drawable. Subsequent calls by any thread to the glXMakeCurrent subroutine using Context have no effect on its viewport.
To release the current context without assigning a new one, call the glXMakeCurrent subroutine with the Drawable and Context parameters set to None and Null, respectively.
The glXMakeCurrent subroutine returns True if it is successful, False otherwise. If False is returned, the previously current rendering context and drawable (if any) remain unchanged.
A process is a single execution environment, implemented in a single address space, consisting of one or more threads.
A thread is one of a set of subprocesses that share a single address space, but maintain separate program counters, stack spaces, and other related global data. A thread is the only member of its subprocess group that is equivalent to a process.
