/** @file gl.h
|
||
|
|
*
|
||
|
|
* Provides an implementation of a GL dispatch layer using a hidden
|
||
|
|
* vtable.
|
||
|
|
*
|
||
|
|
* This is a lower performance path than ifuncs when they are
|
||
|
|
* available, but it is required if you might have multiple return
|
||
|
|
* values for GetProcAddress/dlsym()ed functions. That is the case if
|
||
|
|
* you're using WGL (which can return different function pointers per
|
||
|
|
* context), or if you dlclose() and re-dlopen() libGL (which means
|
||
|
|
* you'll get different dynamically allocated dispatch stubs).
