int cmp_sockaddr	(	sockaddr_t *	addr_1,
		sockaddr_t *	addr_2,
		ignore_port_t	ignore_port
	)

cmp_sockaddr: compare 2 sockaddrs, including ports

Parameters:

addr_1	[IN] first address
addr_2	[IN] second address
ignore_port	[IN] 1 if you want to ignore port comparison, 0 if you need port comparisons

Returns:

1 if addresses match, 0 if they don't

int copy_xprt_addr	(	sockaddr_t *	addr,
		SVCXPRT *	xprt
	)

copy_xprt_addr: copies and transport address into an address field.

copies and transport address into an address field.

Parameters:

addr	[OUT] address field to fill in.
xprt	[IN] transport to get address from.

Returns:

1 if ok, 0 if failure.

unsigned long hash_sockaddr	(	sockaddr_t *	addr,
		ignore_port_t	ignore_port

hash_sockaddr: create a hash value based on the sockaddr_t structure

This creates a native pointer size (unsigned long int) hash value from the sockaddr_t structure. It supports both IPv4 and IPv6, other types can be added in time.

Parameters:

addr	[IN] sockaddr_t address to hash
xprt	[IN] transport to get address from.

Returns:

hash value
