cgGetConnectedStateAssignmentParameter

> # NAME

> cgGetConnectedStateAssignmentParameter - get effect parameter which determines a state assignment's value

> # SYNOPSIS

>       #include <Cg/cg.h>

>       CGparameter cgGetConnectedStateAssignmentParameter( CGstateassignment sa );

> # PARAMETERS

> sa

>   A state assignment whose value is determined using an effect parameter.

> # RETURN VALUES

> Returns the effect parameter used by sa.

> Returns 0 if sa is not using a parameter for its value, if the state assignment is set to an expression, or if an error occurs.

> # DESCRIPTION

> cgGetConnectedStateAssignmentParameter returns the effect parameter from which a given state assignment's value is determined.

> # EXAMPLES

>       /* in Effect.cgfx file */

>       int MyMinFilter;
>       sampler2D Samp = sampler_state {
>          MinFilter = MyMinFilter;
>       };

>       /* in .c/.cpp file */

>       CGparameter sampParam = cgGetNamedEffectParameter( myEffect, "Samp" );
>       CGstateassignment sa = cgGetNamedSamplerStateAssignment( sampParam,
>                                                                "MinFilter" );
>       CGparameter connected = cgGetConnectedStateAssignmentParameter( sa );

> # ERRORS

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

> # HISTORY

> cgGetConnectedStateAssignmentParameter was introduced in Cg 2.0.
