sctp_getpaddrs(3) [freebsd man page]

SCTP_GETPADDRS(3)					   BSD Library Functions Manual 					 SCTP_GETPADDRS(3)

NAME
sctp_getpaddrs, sctp_getladdrs -- return a list of addresses to the caller LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <sys/types.h> #include <sys/socket.h> #include <netinet/sctp.h> int sctp_getpaddrs(int s, sctp_assoc_t asocid, struct sockaddr **addrs); int sctp_getladdrs(int s, sctp_assoc_t asocid, struct sockaddr **addrs); DESCRIPTION
The sctp_getpaddrs() function is used to get the list of the peers addresses. The sctp_getladdrs() function is used to get the list of the local addresses. The association of interest is identified by the asocid argument. The addresses are returned in a newly allocated array of socket addresses returned in the argument addrs upon success. After the caller is finished, the function sctp_freepaddrs() or sctp_freeladdrs() should be used to release the memory allocated by these calls. RETURN VALUES
The call returns -1 upon failure and a count of the number of addresses returned in addrs upon success. ERRORS
The functions can return the following errors: [EINVAL] An address listed has an invalid family or no addresses were provided. [ENOMEM] The call cannot allocate memory to hold the socket addresses. [EBADF] The argument s is not a valid descriptor. [ENOTSOCK] The argument s is not a socket. SEE ALSO

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

NAME
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
