sctp_bindx
- bind or unbind an SCTP socket to a list of addresses.
LIBRARY
Lb libc
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
Fa s
must be a valid SCTP socket descriptor.
The argument
Fa 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
Fa 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 associations in the endpoint will attempt to
have the address(es) added dynamically to the existing
association.
RETURN VALUES
The call returns 0 on success and -1 upon failure.
ERRORS
The
sctp_bindx ();
can return the following errors.
Bq Er EINVAL
This value is returned if the
Fa type
field is not one of the allowed values (see above).
Bq Er ENOMEM
This value is returned if the number of addresses
being added causes a memory allocation failure in
the call.
