I"m trying to find out how to close sockets with a signal handler
function in C without having the socket numbers.

#include
void sighandler(int);
void socket_closer(void);
void sighandler(int signum)
{
socket_closer(); // Close any open sockets...
}
int main(int argc,char * argv)

The scenario is you have a standard C program that opens sockets. The
sockets are used in an infinite loop that never exits. How do you close
these sockets immediately on premature exit?
There is C atexit(), but the problem is that no arguments can be passed
to that. I don't have the integers
