TLS_DONE(3) libdill Library Functions TLS_DONE(3) NAME tls_done - half-closes a TLS protocol SYNOPSIS #include <libdill.h> int tls_done( int s, int64_t deadline); DESCRIPTION WARNING: This is experimental functionality and the API may change in the future. TLS is a cryptographic protocol to provide secure communication over the network. It is a bytestream protocol. This function closes the outbound half of TLS connection. This will, in turn, cause the peer to get EPIPE error after it has received all the data. s: The TLS connection handle. 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. This function is not available if libdill is compiled without --en- able-tls option. RETURN VALUE In case of success the function returns 0. 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. • ENOTSUP: The handle does not support this operation. • EPIPE: The connection was already half-closed. • ETIMEDOUT: Deadline was reached. EXAMPLE int s = tcp_connect(&addr, -1); s = tls_attach_client(s, -1); bsend(s, "ABC", 3, -1); char buf[3]; ssize_t sz = brecv(s, buf, sizeof(buf), -1); s = tls_detach(s, -1); tcp_close(s); SEE ALSO brecv(3) brecvl(3) bsend(3) bsendl(3) now(3) tls_attach_client(3) tls_attach_client_mem(3) tls_attach_server(3) tls_attach_server_mem(3) tls_detach(3) libdill TLS_DONE(3)
