NAME

cgCreateArrayState - create an array-typed state definition

SYNOPSIS

  #include <Cg/cg.h>

  CGstate cgCreateArrayState( CGcontext context,
                              const char * name,
                              CGtype type,
                              int nelements );

PARAMETERS

context

The context in which to define the state.

name

The name of the new state.

type

The type of the new state.

nelements

The number of elements in the array.

RETURN VALUES

Returns a handle to the newly created CGstate.

Returns NULL if there is an error.

DESCRIPTION

cgCreateArrayState adds a new array-typed state definition to context. Before a CgFX file is added to a context, all state assignments in the file must have previously been defined via a call to cgCreateState or cgCreateArrayState.

Applications will typically call cgSetStateCallbacks shortly after creating a new state with cgCreateArrayState.

ERRORS

CG_INVALID_CONTEXT_HANDLE_ERROR is generated if context is not a valid context.

CG_INVALID_PARAMETER_ERROR is generated if name is NULL or not a valid identifier, if type is not a simple scalar, vector, or matrix-type, or if nelements is not a positive number.

HISTORY

cgCreateArrayState was introduced in Cg 1.4.
