Like the subject says, I'm having trouble with select() under Cygwin, when it works
under RedHat 9 and Fedora Core 2 FINAL. The output is shown below for both. And a
bit of code at the bottom.

Some of the code:
void mainLoop(int s)
{
char buff[1024];
int maxfd;
fd_set readSet, writeSet, exceptSet;
struct timeval nullTime, sleepTime;
maxfd = 300;
nullTime.tv_sec = 0;
nullTime.tv_usec = 0;
sleepTime.tv_sec = 0;
sleepTime.tv_usec = SLEEP_TIME; /* 1000000 usec = 1 sec */
while (!finished)
{
if (!firstInfo)
{
FD_ZERO(&readSet);
FD_SET((unsigned int)s, &readSet);
if (select(maxfd + 1, &readSet, (fd_set *)0, (fd_set *)0,
NULL) < 0)
{
fprintf(stderr, "error on select wait: %i\n",
__ERRNO__);
}
}
FD_ZERO(&readSet);
FD_ZERO(&writeSet);
FD_ZERO(&exceptSet);
FD_SET((unsigned int)s, &readSet);
if (select(maxfd + 1, &readSet, &writeSet, &exceptSet, &nullTime) < 0)
{
fprintf(stderr, "error on select polling: %i\n", __ERRNO__);
exit(0);
}
Sorry if it's a bit long, and thanks in advance for any help that can be provided.
