It fails because you are missing the prototype for lseeks, which means that the C compiler is trying to call it with 'int offset' instead of 'off_t offset'. Compile with -Wall.Whats wrong with cygwin?Rather, fix the bugs in your code, and let the compiler help you.
Got it, but why enforcing the use of off_t here? I'm not going to use 64bit offsets. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
