NAME
    cgGetNextState - iterate through states in a context

SYNOPSIS
      #include <Cg/cg.h>

      CGstate cgGetNextState( CGstate state );

PARAMETERS
    state   The current state.

RETURN VALUES
    Returns the next state in the context's internal sequence of states.

    Returns NULL when state is the last state in the context.

DESCRIPTION
    The states within a context can be iterated over using cgGetNextState.

    Note that no specific order of traversal is defined by this mechanism.
    The only guarantee is that each state will be visited exactly once. No
    guarantees can be made if states are created or deleted during
    iteration.

EXAMPLES
      CGstate state = cgGetFirstState( context );
      while( state )
      {
        /* do something with state */
        state = cgGetNextState( state )
      }

ERRORS
    CG_INVALID_STATE_HANDLE_ERROR is generated if state is not a valid
    state.

HISTORY
    cgGetNextState was introduced in Cg 1.4.
