NAME
    cgGetArrayParameter - get a parameter from an array

SYNOPSIS
      #include <Cg/cg.h>

      CGparameter cgGetArrayParameter( CGparameter param,
                                       int index );

PARAMETERS
    param   The array parameter handle.

    index   The index into the array.

RETURN VALUES
    Returns the parameter at the specified index of param if param
    references an array, and the index is valid.

    Returns NULL otherwise.

DESCRIPTION
    cgGetArrayParameter returns the parameter of array param specified by
    index. cgGetArrayParameter is used when inspecting elements of an array
    parameter in a program.

EXAMPLES
      CGparameter array = ...; /* some array parameter */
      int array_size = cgGetArraySize( array );
      for(i=0; i < array_size; ++i)
      {
        CGparameter element = cgGetArrayParameter(array, i);
        /* Do stuff with element */
      }

ERRORS
    CG_INVALID_PARAM_HANDLE_ERROR is generated if param is not a valid
    parameter.

    CG_ARRAY_PARAM_ERROR is generated if param is not an array parameter.

    CG_OUT_OF_ARRAY_BOUNDS_ERROR is generated if index is outside the bounds
    of param.

HISTORY
    cgGetArrayParameter was introduced in Cg 1.1.
