NAME
    cgIsParameter - determine if a CGparameter references a valid Cg
    parameter object

SYNOPSIS
      #include <Cg/cg.h>

      CGbool cgIsParameter( CGparameter param );

PARAMETERS
    param   Specifies the parameter handle to check.

DESCRIPTION
    cgIsParameter returns CG_TRUE if param references a valid parameter
    object. This function is typically used for iterating through the
    parameters of an object. It can also be used as a consistency check when
    the application caches CGparameter handles. Certain program operations
    like deleting the program or context object that the parameter is
    contained in will cause a parameter object to become invalid.

RETURN VALUES
    Returns CG_TRUE if param references a valid parameter object.

    Returns CG_FALSE otherwise.
