## Functions

VLGRAPHICS_EXPORT bool | vl::initializeOpenGL ()
| To test whether OpenGL has been initialized at least once check vl::Is_OpenGL_Initialized.
VLGRAPHICS_EXPORT void * | vl::getGLProcAddress (const char *name)
| Returns the address of the specified OpenGL function if supported by the active OpenGL driver and profile.
VLGRAPHICS_EXPORT const char * | vl::getGLErrorString (int err)
| Returns a readable string corresponding to the given OpenGL error code as returned by glGetError()
VLGRAPHICS_EXPORT int | vl::glcheck (const char *file, int line)
