status.i4.v = swap_bytes_longword_c(array.i4a.r, num_elements.i4.v)

	This routine swaps bytes in a longword array resulting in the
	original byte order being inverted.  (0123 -> 3210)

	array		longword array to byte swap
	num_elements	number of elements in array

	This function returns ACNET status values as follows:

	OK			success
	CLIB_INVARG		invalid number of elements

	This function requires the following include files:

	C/C++ usage:

	int	status;
	int	array[NUM_ELEMENTS];
	int	num_elements = NUM_ELEMENTS;

	status = swap_bytes_longword_c(array,num_elements);
