NAME
cgGetParameterBaseResource - get a program parameter's base resource
SYNOPSIS
#include <Cg/cg.h> CGresource cgGetParameterBaseResource( CGparameter param );PARAMETERS
- param
Specifies the program parameter.
DESCRIPTION
cgGetParameterBaseResource allows the application to retrieve the base resource for a parameter in a Cg program. The base resource is the first resource in a set of sequential resources. For example, if a given parameter has a resource of CG_ATTR7, it's base resource would be CG_ATTR0. Only parameters with resources whose name ends with a number will have a base resource. All other parameters will return the undefined resource CG_UNDEFINED when calling cgGetParameterBaseResource.
The numerical portion of the resource may be retrieved with the cgGetParameterResourceIndex function. For example, if the resource for a given parameter is CG_ATTR7, cgGetParameterResourceIndex will return 7.
RETURN VALUES
Returns the base resource of param. If no base resource exists for the given parameter, CG_UNDEFINED is returned.
ERRORS
CG_INVALID_PARAM_HANDLE_ERROR is generated if the handle param is invalid.
CG_INVALID_PARAMETER_ERROR is generated if the parameter is not a leaf node.
