mongoc_socket_connect — mongoc_socket_connect()
int mongoc_socket_connect (mongoc_socket_t *sock, const struct sockaddr *addr, mongoc_socklen_t addrlen, int64_t expire_at);
sock: A mongoc_socket_t.
addr: A struct sockaddr.
addrlen: A mongoc_socklen_t.
expire_at: A int64_t containing the absolute timeout using the monotonic clock.
This function is a wrapper around the BSD socket connect() interface. It provides better portability between UNIX-like and Microsoft Windows platforms.
This function performs a socket connection but will fail if expire_at has been reached by the monotonic clock. Keep in mind that this is an absolute timeout in milliseconds. You should add your desired timeout to System Clock.
0 if successful, -1 on failure and errno is set.
