SCTP_BINDX(3) BSD Library Functions Manual SCTP_BINDX(3)NAMEsctp_bindx — bind or unbind an SCTP socket to a list of addresses.
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/sctp.h>
int
sctp_bindx(int s, struct sockaddr *addrs, int num, int type);
DESCRIPTION
The sctp_bindx() call binds or unbinds a address or a list of addresses
to an SCTP endpoint. This allows a user to bind a subset of addresses.
The sctp_bindx() call operates similarly to bind() but allows a list of
addresses and also allows a bind or an unbind. The argument s must be a
valid SCTP socket descriptor. The argument addrs is a list of addresses
(where the list may be only 1 in length) that the user wishes to bind or
unbind to the socket. The argument type must be one of the following
values.
SCTP_BINDX_ADD_ADDR This value indicates that the listed address(es) need
to be added to the endpoint.
SCTP_BINDX_DEL_ADDR This value indicates that the listed address(es) need
to be removed from the endpoint.
Note that when a user adds or deletes an address to an association if the
dynamic address flag net.inet.sctp.auto_asconf is enabled any associa‐
tions in the endpoint will attempt to have the address(es) added dynami‐
cally to the existing association.
RETURN VALUES
The call returns 0 on success and -1 upon failure.
ERRORS
The sctp_bindx() function can return the following errors:
[EINVAL] This value is returned if the type field is not one of
the allowed values (see above).
[ENOMEM] This value is returned if the number of addresses
being added causes a memory allocation failure in the
call.
[EBADF] The argument s is not a valid descriptor.
[ENOTSOCK] The argument s is not a socket.
