ssize_t mongoc_socket_recv (mongoc_socket_t *sock, void *buf, size_t buflen, int flags, int64_t expire_at);
sock: A mongoc_socket_t.
buf: A buffer to read into.
buflen: A size_t with the number of bytes to receive.
flags: flags for recv().
expire_at: A int64_t with the time to expire in monotonic time using System Clock, which is in microseconds.
