That is the case if * you're using WGL (which can return different function pointers per * context), or if you dlclose() and re-dlopen() libGL (which means * you'll get different dynamically allocated dispatch stubs). */ #ifndef __EPOXY_GL_H #define __EPOXY_GL_H #if defined(__gl_h_) || defined(__glext_h_) #error epoxy/gl.h must be included before (or in place of) GL/gl.h #else #define __gl_h_ #define __glext_h_ #endif #include "epoxy/gl_common.h" #include "epoxy/gl_generated.h" #include "epoxy/gl_generated_vtable_defines.h" #endif /* __EPOXY_GL_H */
