sctp_bindx – bind or unbind an SCTP socket to a list of addresses

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_bindx(int s, struct sockaddr *addrs, int num, int type);

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_REM_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.

The call returns 0 on success and -1 upon failure.

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.
