Hi all,
I tried the following program on my machine.
( CYGWIN_NT-5.0 1.1.4(0.26/3/2) 2000-08-03 20:53 win2k)
#include <stdio.h>
#include <signal.h>
#include <errno.h>
void sigfunc(int sig)
{
fprintf(stderr, "received signal=%d\n", sig);
exit(1);
}
main()
{
char rdt[8];
signal(SIGTERM, sigfunc);
while (1)
{
fprintf(stderr,"read wait -> ");
read(0, rdt, 1);
fprintf(stderr,"read return %d\n", errno);
if (errno != EINTR)
break;
}
}
When I kill this program, I see the following.
read wait -> read return 4
read wait -> read return 4
read wait -> read return 4
........
(inifinite loop)
Is this a expected behavior ?
Note that sigfunc() isn't called.
Regards.
