Function Documentation

mptcpd_sockaddr_copy()

struct sockaddr * mptcpd_sockaddr_copy

(

struct sockaddr const *

sa

)

Deep copy a sockaddr.

Copy the address family-specific contents of a sockaddr. For an AF_INET address family, a struct sockaddr_in will be dynamically allocated and copied from sa. Similarly, struct sockaddr_in6 will be allocated and copied from sa for the AF_INET6 address family case.

Returns

Dynamically allocated copy of sa if the sa_family member is AF_INET or AF_INET6, and NULL otherwise. Deallocate with l_free().

mptcpd_sockaddr_storage_init()

bool mptcpd_sockaddr_storage_init	(	in_addr_t const *	addr4,
		struct in6_addr const *	addr6,
		in_port_t	port,
		struct sockaddr_storage *	addr
	)

Initialize sockaddr_storage instance.

Initialize a sockaddr_storage instance with the provided IPv4 or IPv6 address. Only one is required and used. The port may be zero in cases where it is optional.

Parameters

[in]	addr4	IPv4 internet address (network byte order).
[in]	addr6	IPv6 internet address.
[in]	port	TCP port (network byte order).
[in,out]	addr	mptcpd network address information.

Returns

true on success. false otherwise.
