SCTP_GETPADDRS(3) FreeBSD Library Functions Manual SCTP_GETPADDRS(3)

NAME

sctp_getpaddrs, sctp_getladdrsreturn 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.
