sctp_getpaddrs, sctp_getladdrs – return a list of addresses to the caller

LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES ERRORS SEE ALSO

Standard C Library (libc, -lc)

#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);

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.

The call returns -1 upon failure and a count of the number of addresses returned in addrs upon success.

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.
