NAME
cgGetParameterBaseType - get a program parameter's base type
SYNOPSIS
#include <Cg/cg.h> CGtype cgGetParameterBaseType( CGparameter param );PARAMETERS
- param
Specifies the parameter.
DESCRIPTION
cgGetParameterBaseType allows the application to retrieve the base type of a parameter.
If param is of a numeric type (scalar, vector, or matrix), the scalar enumerant corresponding to param's type will be returned. For example, if param is of type CG_FLOAT4x3, cgGetParameterBaseType will return CG_FLOAT.
If param is an array, the base type of the array elements will be returned.
If param is a structure, its type-specific enumerant will be returned, as per cgGetParameterNamedType.
Otherwise, param's type enumerant will be returned.
RETURN VALUES
Returns the base type enumerant of param. If an error occurs, CG_UNKNOWN_TYPE will be returned.
ERRORS
CG_INVALID_PARAM_HANDLE_ERROR is generated if param does not refer to a valid parameter.
