Description [src]

Gets a pointer to a given GL or GL ES extension function. This acts as a wrapper around glXGetProcAddress() or whatever is the appropriate function for the current backend.

This function should not be used to query core opengl API symbols since eglGetProcAddress for example doesn’t allow this and and may return a junk pointer if you do.

The value is a NUL terminated UTF-8 string.
