sctp_getladdrs: Returns all locally bound addresses on a socket.
NAMEsctp_getladdrs - Returns all locally bound addresses on a socket.
#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);
DESCRIPTIONsctp_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.
