SYNOPSIS
  #include <Cg/cgGL.h>

DESCRIPTION
The cgGLGetParameter functions extract the values set by cgGLSetParameter functions.

There are versions of the function that take either float or double values signified by f or d in the function name.

Each function returns either 1, 2, 3, or 4 values.

These functions may only be called with uniform numeric parameters.

CG_INVALID_PROFILE_ERROR is generated if param's profile is not a supported OpenGL profile.

CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.

HISTORY
The cgGLGetParameter functions were introduced in Cg 1.1.
