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

SYNOPSIS
      #include <Cg/cg.h>

      CGparameter cgGetSamplerStateAssignmentParameter( CGstateassignment sa );

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.
