GLPH_LOAD_FUNCS_GC(), GLPH_LOAD_FUNCS_IDX()

Load GLPh functions

Synopsis:

#define GLPH_LOAD_FUNCS_GC ( gc ) ...
#define GLPH_LOAD_FUNCS_IDX ( n ) ...

Arguments:

gc

GLPH_LOAD_FUNCS_GC() only. A QNXGL context, as returned by qnxgl_buffers_create(), to load the functions from.

n

GLPH_LOAD_FUNCS_IDX() only. The index of an OpenGL renderer to load the functions from.

Library:

GL

Description:

Use these macros to load GLPh extension functions based on a QNXGL context (gc) or renderer index (n). You should call one of these macros after creating your first graphics context and have detected GL_QNX_glph in the extensions string (using glGetString(GL_EXTENSIONS)). These macros assume that the source file has already declared the function pointers, for example using GLPH_DECLARE_FUNCS or GLPH_DECLARE_EXTERN_FUNCS.

Classification:

Neutrino
