tls_done - half-closes a TLS protocol
#include <libdill.h> int tls_done( int s, int64_t deadline);
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 milliseconds. Use the now function to get your current point in time. 0 means immediate timeout, i.e., perform the operation if possible or return 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 --disable-sockets option.
This function is not available if libdill is compiled without --enable-tls option.
In case of success the function returns 0. In case of error it returns -1 and sets errno to one of the values below.
int s = tcp_connect(&addr, -1); s = tls_attach_client(s, -1); bsend(s, "ABC", 3, -1); char buf; ssize_t sz = brecv(s, buf, sizeof(buf), -1); s = tls_detach(s, -1); tcp_close(s);
