31 Get a string terminated by an '\n' (matches interface of fgets).

33 the length of the buffer (including the trailing \0)
34 returns length of buffer on success, -1 on failure.

44 Write a chunk of bytes to the socket (matches interface of fwrite).
45 Returns number of bytes successfully written.

55 Send formatted output to the socket (matches interface of fprintf).
56 Returns number of bytes successfully written.
