SCTP_BINDX(3) Linux Programmer's Manual SCTP_BINDX(3)
sctp_bindx - Add or remove bind addresses on a socket.
#include <sys/types.h> #include <sys/socket.h> #include <netinet/sctp.h> int sctp_bindx(int sd, struct sockaddr * addrs, int addrcnt, int flags);
sctp_bindx adds or removes a set of bind addresses passed in the array addrs to/from the socket sd. addrcnt is the number of addresses in the array and the flags paramater indicates if the addresses need to be added or removed. If sd is an IPv4 socket, the addresses passed must be IPv4 addresses. If sd is an IPv6 socket, the addresses passed can be either IPv4 or IPv6 addresses. addrs is a pointer to an array of one or more socket addresses. Each address is contained in its appropriate structure(i.e. struct sockaddr_in or struct sockaddr_in6). The family of the address type must be used to distinguish the address length. The caller specifies the number of addresses in the array with addrcnt. The flags parameter can be either SCTP_BINDX_ADD_ADDR or SCTP_BINDX_REM_ADDR. An application can use SCTP_BINDX_ADD_ADDR to associate additional addresses with an endpoint after calling bind(2). SCTP_BINDX_REM_ADDR directs SCTP to remove the given addresses from the association. A caller may not remove all addresses from an association. It will fail with EINVAL.
On success, 0 is returned. On failure, -1 is returned, and errno is set appropriately.
EBADF sd is not a valid descriptor. ENOTSOCK sd is a descriptor for a file, not a socket. EFAULT Error while copying in or out from the user address space. EINVAL Invalid port or address or trying to remove all addresses from an association. EACCES The address is protected, and the user is not the super- user.
