SDL_GL_GetProcAddress(3)       SDL API Reference      SDL_GL_GetProcAddress(3)

NAME
       SDL_GL_GetProcAddress- Get the address of a GL function

SYNOPSIS
       #include "SDL.h"

       void *SDL_GL_GetProcAddress(const char* proc);

DESCRIPTION
       Returns the address of the GL function proc, or NULL if the function is
       not found. If the GL library is loaded at runtime, with	SDL_GL_LoadLi‚Äź
       brary,  then  all GL functions must be retrieved this way. Usually this
       is used to retrieve function pointers to OpenGL extensions.

EXAMPLE
       typedef void (*GL_ActiveTextureARB_Func)(unsigned int);
       GL_ActiveTextureARB_Func glActiveTextureARB_ptr = 0;
       int has_multitexture=1;
       .
       .
       .
       /* Get function pointer */
       glActiveTextureARB_ptr=(GL_ActiveTextureARB_Func) SDL_GL_GetProcAddress("glActiveTextureARB");

       /* Check for a valid function ptr */
       if(!glActiveTextureARB_ptr){
	 fprintf(stderr, "Multitexture Extensions not present.
       ");
	 has_multitexture=0;
       }
       .
       .
       .
       .
       if(has_multitexture){
	 glActiveTextureARB_ptr(GL_TEXTURE0_ARB);
	 .
	 .
       }
       else{
	 .
	 .
       }
