SCTP_BINDX(3) Library Functions Manual SCTP_BINDX(3) NAME sctp_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 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() function can return the following errors: [EBADF] The argument s is not a valid descriptor. [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. [ENOTSOCK] The argument s is not a socket.
