Hi,
I'm trying to disable/ignore the ctrl+c in a c++ program.
I did it alot on UNIX but somehow it doens't work on WindowsXP,
I'm using the right function and typedefs but still....nothing.

I'm doing something like:

void someFunction(int sigNum){
signal (SIGINT,somefunction);
cout<<"eh eh, you can't use ctrl+c"<<endl;
}

main(){
signal(SIGINT,somefunction);

/*
Shell program
*/
}

I debuged the code and it looks like it's doesn't get into the someFunction at all and terminates and program as if I didn't use the signal function.

Any ideas?
thanks a lot.

I don't have any problems using this test program:

(Toggle Plain Text)

#include <iostream>
#include <csignal>

using namespace std;

void sig_handler ( int )
{
 signal ( SIGINT, sig_handler );
 cout<<"Interactive attention disabled"<<endl;
}

int main()
{
 signal ( SIGINT, sig_handler );

 while ( 1 )
  ;
}

Try it and see if you still have the same problem.
