warning: implicit declaration of function 'kill'

Question

I am making these inclusions:

#include 
#include 
#include 
#include 

But

Answer 1

You are probably passing the "-ansi -Wall" switches to the gcc compiler. You can remove "-ansi" if you don't need it, otherwise try to set the proper feature define macro.

Something like:

#define _POSIX_SOURCE
#include 
#include 
#include 
#include
