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
    cgGetSamplerStateAssignmentParameter returns a handle to a parameter. If
    sa is not a state assignment in a sampler_state block, NULL is returned.

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
    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.

ERRORS
    CG_INVALID_STATE_ASSIGNMENT_HANDLE_ERROR is generated if sa does not
    refer to a valid state assignment.

HISTORY
    cgGetSamplerStateAssignmentParameter was introduced in Cg 1.4.
