c - How to set a timeout for connect() and how to measure it? -


i writing small network utility, in somewhere in code have following lines:

if (connect(sock, addr_result->ai_addr, addr_result->ai_addrlen) < 0)   syserr("connect");

i have 2 questions regarding timeouts:

  1. how can set timeout connect() using linux api?
  2. if wanted measure timeout myself, correct way this?

register signal handler sigalarm. set alarm before calling connect , clear alarm after connect returns, if hit signal handler it's connection timeout.
