common_transform_num_const_c

	num_constants.i4.v = common_transform_num_const_c(common_index.i4.v)

	This function is called to return the required number of constants
	for the common transform specified.

	common_index	common transform index

	This function returns status values as follows:

	DIO_BADARG		invalid common_index passed
	otherwise		number of constants in transform

	This function requires the following include files:
