chkabort
NAME
chkabort - check for ^C and take the appropriate action
SYNOPSIS
(void) chkabort(void);
FUNCTION
Checks for a ^C and takes the appropriate action. If the appropriate
action is to exit than this routine does not return. stdio and other
routines will call chkabort() at various points.
The action taken by ^C may be set by the signal() or onbreak() calls.
EXAMPLE
/*
* wait for somebody to hit ^C (note that this is very wasteful of
* CPU and thus isn't a real good example).
*/
main()
{
int i;
for (i = 0; i < 10000000; ++i)
chkabort();
return(0);
}
