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.
This function performs a recv() on the underlying socket.
The number of bytes received on success, 0 on stream closed, and -1 if there was a failure and errno is set.
