Linux strange newline "\n" problem - messes up program

[manontheedge]

I'm getting weird results in my program, and even compile time errors, and I've got it down to the "\n" command I use in "printf()".

The program this is happening in deals with multiple processes, so I'm forking and killing processes during the program. The code runs perfectly fine, UNTIL I try to use printf() with ANYTHING containing "\n" ... doesn't matter how many of them there are in the printf() statement, it always either gives a compile time error or causes really strange program errors during run time.

I'm fairly new to Linux ... is there something I don't know about using the newline character causing weird glitches???

I actually just realised that the problem doesn't have to do with the newline character, it has to do with the include files I'm using...

#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <signal.h>

if I have multiple words inside the printf() statement I get compile time errors. Why is this happening? Is "signal.h" messing something up? I'm using "signal.h" because I'm using the KILL command in my code.

Let's see your printf() and the specific errors you are getting.
