.Dd June 14, 2015 .Dt SCTP_BINDX 3 .Os .Sh NAME .Nm sctp_bindx .Nd bind or unbind an SCTP socket to a list of addresses .Sh LIBRARY .Lb libc .Sh SYNOPSIS n sys/types.h n sys/socket.h n netinet/sctp.h .Ft int .Fn sctp_bindx "int s" "struct sockaddr *addrs" "int num" "int type" .Sh DESCRIPTION The .Fn 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 .Fn sctp_bindx call operates similarly to .Fn 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.

p .Dv SCTP_BINDX_ADD_ADDR This value indicates that the listed address(es) need to be added to the endpoint.

p .Dv SCTP_BINDX_REM_ADDR This value indicates that the listed address(es) need to be removed from the endpoint.

p Note that when a user adds or deletes an address to an association if the dynamic address flag .Va 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. .Sh RETURN VALUES The call returns 0 on success and -1 upon failure. .Sh ERRORS The .Fn sctp_bindx function can return the following errors: l -tag -width Er t Bq Er EINVAL This value is returned if the .Fa type field is not one of the allowed values (see above). t Bq Er ENOMEM This value is returned if the number of addresses being added causes a memory allocation failure in the call. t Bq Er EBADF The argument .Fa s is not a valid descriptor. t Bq Er ENOTSOCK The argument .Fa s is not a socket. .El .Sh SEE ALSO .Xr bind 2 , .Xr sctp 4
