status.i4.v = structure_size_c(name.i1a.r, size.u4.r)

	This routine returns the length of a named structure in bytes.

	name		null terminated structure name
			(Note: The name format is [{class}.]{struct}.)
	size		returned size in bytes

	This function returns status values as follows:

	OK			success
	CLIB_MEMFAIL		dynamic memory allocation failed
	CLIB_NO_SUCH		structure name was not found

	This function requires the following include files:

	cbslib_h, acnet_errors_h
