NAME

SDL_GL_!GetProcAddress?- Get the address of a GL function

SYNOPSIS

#include

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_!LoadLibrary?, 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?(
