cgGLUnloadProgram

> # NAME

> cgGLUnloadProgram - destroy the OpenGL shader object associated with a program

> # SYNOPSIS

>       #include <Cg/cgGL.h>

>       void cgGLUnloadProgram( CGprogram program );

> # PARAMETERS

> program

>   The program for which to destroy the shader object. The CGprogram handle is still valid after this call.

> # RETURN VALUES

> None.

> # DESCRIPTION

> cgGLUnloadProgram destroys the OpenGL shader object for a program.

> This call does not destroy the CGprogram itself, only the associated GL shader object. Use cgDestroyProgram to free the CGprogram itself. Also note that freeing a CGprogram using the core runtime implicitly calls this routine to avoid resource leaks.

> # EXAMPLES

>       // prog is a CGprogram initialized elsewhere
>       ...
>       cgGLUnloadProgram(prog);

>       CGbool loaded = cgGLIsProgramLoaded(prog);  // loaded == CG_FALSE

> # ERRORS

> CG_INVALID_PROGRAM_HANDLE_ERROR is generated if program is not a valid program handle.

> # HISTORY

> cgGLUnloadProgram was introduced in Cg 2.1.
