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

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

43 Returns number of bytes successfully written.

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