SCTP_GETLADDRS(3)					     Linux Programmer's Manual						 SCTP_GETLADDRS(3)

sctp_getladdrs - Returns all locally bound addresses on a socket. SYNOPSIS
#include <sys/types.h> #include <sys/socket.h> #include <netinet/sctp.h> int sctp_getladdrs(int sd, sctp_assoc_t assoc_id, struct sockaddr **addrs); void sctp_freeladdrs(struct sockaddr *addrs); DESCRIPTION
sctp_getladdrs returns all locally bound addresses on a socket. On return, addrs will point to a dynamically allocated packed array of sockaddr structures of the appropriate type for each local address. The caller should use sctp_freeladdrs to free the memory. Note that the in/out parameter addrs must not be NULL. If sd is an IPv4 socket, the addresses returned will be all IPv4 addresses. If sd is an IPv6 socket, the addresses returned can be a mix of IPv4 or IPv6 addresses. For one-to-many style sockets, id specifies the association to query. For one-to-one style sockets, id is ignored. If the id field is set to 0, then the locally bound addresses are returned without regard to any particular association. sctp_freeladdrs frees all the resources allocated by sctp_getladdrs RETURN VALUE
On success, sctp_getladdrs returns the number of local addresses bound to the socket. If the socket is unbound, 0 is returned and the value of *addrs is undefined. On error, sctp_getladdrs returns -1 and the value of *addrs is undefined. SEE ALSO

sctp_getladdrs, sctp_freeladdrs - returns all locally bound addresses on an SCTP socket SYNOPSIS
cc [ flag... ] file... -lsocket -lnsl -lsctp [ library... ] #include <sys/types.h> #include <sys/socket.h> #include <netinet/sctp.h> int sctp_getladdrs(int sock, sctp_assoc_t id, void **addrs); void sctp_freeladdrs(void *addrs); DESCRIPTION
The sctp_getladdrs() function queries addresses to which an SCTP socket is bound. The sctp_freeladdrs() function releases resources that are allocated to hold the addresses. The sctp_getladdrs() function returns all the locally bound addresses on the SCTP socket sock. On completion addrs points to a dynamically allocated array of sockaddr_in structures for an Internet Protocol (IPv4) socket or an array of sockaddr_in6 structures for an Internet Protocol Version 6 (IPv6) socket. The addrs parameter must not be NULL. For an IPv4 SCTP socket, the addresses returned in the sockaddr_in structures are IPv4 addresses. For an IPv6 SCTP socket, the addresses in the sockaddr_in6 structures can be IPv6 addresses or IPv4-mapped IPv6 addresses. If sock is a one-to-many style SCTP socket, id specifies the association of interest. A value of 0 to id returns locally-bound addresses regardless of a particular association. If sock is a one-to-one style SCTP socket, id is ignored. The sctp_freeladdrs() function frees the resources allocated by sctp_getladdrs(). The addrs parameter is the array of addresses allocated by sctp_getladdrs(). RETURN VALUES
Upon successful completion, the sctp_getladdrs() function returns the number of addresses in the addrs array. Otherwise, the function returns -1 and sets errno to indicate the error. ERRORS
The sctp_getladdrs() call fails under the following conditions. EBADF The sock argument is an invalid file descriptor. ENOTSOCK The sock argument is not a socket. EINVAL The addrs argument is NULL. EINVAL The id argument is an invalid socket. ATTRIBUTES
