Function Documentation

◆ _lf_multiport_iterator_impl()

lf_multiport_iterator_t _lf_multiport_iterator_impl	(	lf_port_base_t **	port,
		int	width )

Given an array of pointers to port structs, return an iterator that can be used to iterate over the present channels.

Parameters

port	An array of pointers to port structs.
width	The width of the multiport (or a negative number if not a multiport).

◆ compare_sizes()

int compare_sizes	(	const void *	a,
		const void *	b )

Compare two non-negative integers pointed to. Return -1 if a < b, 0 if a == b, and 1 if a > b.

Parameters

a	Pointer to the first integer.
b	Pointer to the second integer.

◆ lf_multiport_next()

int lf_multiport_next ( lf_multiport_iterator_t * iterator )

Return the channel number of the next present input on the multiport or -1 if there are no more present channels.

Parameters

iterator The iterator.
