+SDL_GL_GetProcAddress \- Get the address of a GL function
+.SH "SYNOPSIS"
+.PP
+\fB#include "SDL\&.h"
+.sp
+\fBvoid *\fBSDL_GL_GetProcAddress\fP\fR(\fBconst char* proc\fR);
+.SH "DESCRIPTION"
+.PP
+Returns the address of the GL function \fBproc\fR, or \fBNULL\fR if the function is not found\&. If the GL library is loaded at runtime, with \fI\fBSDL_GL_LoadLibrary\fP\fR, then \fIall\fP GL functions must be retrieved this way\&. Usually this is used to retrieve function pointers to OpenGL extensions\&.
