Cg OpenGL Runtime API                        cgGLUnloadProgram(3)



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

SYNOPSIS
       #include 

       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 == CGFALSE


ERORS
     CGINVALIDPROGRAMHANDLEROR is generated if program is
     not a valid program handle.

HISTORY
     cgGLUnloadProgram was introduced in Cg 2.1.
