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().
