SYNOPSIS
      #include <Cg/cg.h>

DESCRIPTION
    cgGetParameterSemantic allows the application to retrieve the semantic
    of a parameter in a Cg program. If a uniform parameter does not have a
    user-assigned semantic, an empty string will be returned. If a varying
    parameter does not have a user-assigned semantic, the semantic string
    corresponding to the compiler-assigned resource for that varying will be
    returned.

EXAMPLES

ERRORS
    CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid
    parameter.

HISTORY
    cgGetParameterSemantic was introduced in Cg 1.1.
