status.i4.v = dio_set_hash_table_size_c(table_size.u4.v)

	This routine sets the hash table size for cached DIO information.
	If it is successful, all previously cached information will be
	delete.  This routine may be useful if you are accessing a great
	number of devices to speed up retrieval of cached information.

	table_size	desired length of has table (>= 128)

	This function returns ACNET status values as follows:

	OK			success
	DIO_BADARG		invalid table size passed
	DIO_DUPREQ		requested size is the same as the current size

	This function requires the following include files:

	diolib_h, acnet_errors_h
