SUFFIX_DETACH(3) libdill Library Functions SUFFIX_DETACH(3) NAME suffix_detach - terminates SUFFIX protocol and returns the underlying socket SYNOPSIS #include <libdill.h> int suffix_detach( int s, int64_t deadline); DESCRIPTION SUFFIX is a message-based protocol that delimits messages by specific byte sequences. For example, many protocols are line-based, with indi- vidual messages separated by CR+LF sequence. This function does the terminal handshake and returns underlying socket to the user. The socket is closed even in the case of error. s: Handle of the SUFFIX socket. deadline: A point in time when the operation should time out, in mil- liseconds. Use the now function to get your current point in time. 0 means immediate timeout, i.e., perform the operation if possible or re- turn without blocking if not. -1 means no deadline, i.e., the call will block forever if the operation cannot be performed. This function is not available if libdill is compiled with --dis- able-sockets option. RETURN VALUE In case of success the function returns underlying socket handle. In case of error it returns -1 and sets errno to one of the values below. ERRORS • EBADF: Invalid handle. • ECANCELED: Current coroutine was canceled. • ECONNRESET: Broken connection. • ENOTSUP: The handle is not a SUFFIX protocol handle. • ETIMEDOUT: Deadline was reached. EXAMPLE int s = tcp_connect(&addr, -1); s = suffix_attach(s, " ", 2); msend(s, "ABC", 3, -1); char buf[256]; ssize_t sz = mrecv(s, buf, sizeof(buf), -1); s = suffix_detach(s, -1); tcp_close(s); SEE ALSO mrecv(3) mrecvl(3) msend(3) msendl(3) now(3) suffix_attach(3) suf- fix_attach_mem(3) libdill SUFFIX_DETACH(3)
