> # PARAMETERS

> program

>   The program for which the OpenGL program ID will be retrieved.

> # RETURN VALUES

> Returns a GLuint associated with the GL program object for profiles that use program object.

> Returns 0 for profiles that do not have OpenGL programs (e.g. fp20).

> # DESCRIPTION

> cgGLGetProgramID returns the identifier to the OpenGL program object associated with program. cgGLGetProgramID should not be called before cgGLLoadProgram is called.

> # EXAMPLES
