> cgGetSamplerStateAssignmentParameter - get the sampler parameter being set up given a state assignment in its sampler_state block

> # SYNOPSIS

>       #include <Cg/cg.h>

> # PARAMETERS

> sa

>   The state assignment in a sampler_state block

> # RETURN VALUES

> Returns a handle to a parameter.

> Returns NULL if sa is not a 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.

> # EXAMPLES

> Given an effect file with:

>       sampler2D foo = sampler_state { GenerateMipmap = true; }

> cgGetSamplerStateAssignmentParameter returns a handle to foo if passed a handle to the GenerateMipmap state assignment.

> # ERRORS

> CG_INVALID_STATE_ASSIGNMENT_HANDLE_ERROR is generated if sa is not a valid state assignment.
