Functions
ELL Hash Functions For IP Addresses
A set of types and functions for using an IP address through a struct sockaddr as the key for an ELL hashmap (struct l_hashmap). Note These functions are only used internally, and are not exported from libmptcpd.
int	mptcpd_hash_sockaddr_compare (void const *a, void const *b)
	Compare hash map keys based on IP address alone.
void *	mptcpd_hash_sockaddr_key_copy (void const *p)
	Deep copy the hash map key p.
void	mptcpd_hash_sockaddr_key_free (void *p)

Function Documentation

mptcpd_hash_sockaddr_compare()

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

Compare hash map keys based on IP address alone.

Parameters

[in]	a	Pointer struct sockaddr (left hand side).
[in]	b	Pointer struct sockaddr (right hand side).

Returns

0 if the IP addresses are equal, and -1 or 1 otherwise, depending on IP address family and comparisons of IP addresses of the same type.

Note

Ports are not compared.

mptcpd_hash_sockaddr_key_copy()

void * mptcpd_hash_sockaddr_key_copy

(

void const *

p

)

Deep copy the hash map key p.

Returns

The dynamically allocated deep copy of the hash map key p. Deallocate with l_free().
