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.
Examples

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.
