1991-2006 Silicon Graphics, Inc. glXGetProcAddress 3G glXGetProcAddress obtain a pointer to an OpenGL or GLX function void(*)() glXGetProcAddress const GLubyte * procName procName Specifies the name of the OpenGL or GLX function whose address is to be returned. glXGetProcAddress returns the address of the function specified in procName. This is necessary in environments where the OpenGL link library exports a different set of functions than the runtime library. A NULL pointer is returned if function requested is not suported in the implementation being queried. GLU functions are not queryable due to the fact that the library may not be loaded at the time of the query. Copyright 1991-2006 Silicon Graphics, Inc.
