NAME

cgGetFirstDependentParameter - get the first dependent parameter from a parameter

SYNOPSIS

  #include <Cg/cg.h>

  CGparameter cgGetFirstDependentParameter(CGparameter param);

PARAMETERS

param

Specifies the parameter.

DESCRIPTION

cgGetFirstDependentParameter returns the first member dependent parameter associated with a given parameter. The rest of the members may be retrieved from the first member by iterating with the cgGetNextParameter() function.

Dependent parameters are parameters that have the same name as a given parameter but different resources. They only exist in profiles that have multiple resources associated with one parameter.

RETURN VALUES

cgGetFirstDependentParameter returns a handle to the first member parameter.

NULL is returned if param is not a struct or if some other error occurs.

ERRORS

CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid parameter.
