SYNOPSIS
#include <Cg/cg.h> CGparameter cgGetSamplerStateAssignmentParameter(CGstateassignment sa);PARAMETERS
- sa
Specifies the state assignment in a sampler_state block
DESCRIPTION
Given the handle to a state assignment in a sampler_state block in an effect file, cgGetSamplerStateAssignmentParameter returns a handle to the sampler parameter being initialized. For example, given an effect file with:
sampler2D foo = sampler_state { GenerateMipmap = true; }If sa is a handle to the GenerateMipmap state assignment, then cgGetSamplerStateAssignmentParameter returns a handle to foo.
RETURN VALUES
cgGetSamplerStateAssignmentParameter returns a handle to a parameter. If sa is not a state assignment in a sampler_state block, NULL is returned.
ERRORS
CG_INVALID_STATE_ASSIGNMENT_HANDLE_ERROR is generated if sa does not refer to a valid state assignment.
