We are using a stock redhat 5.1 in an embedded system.
It is not on the internet, and has _very_ few services. (for
you hacker types).
If this is on the wrong list, please point me to a
better list. thanks!
we opened a pipe without error. we then did this:
FD_ZERO(&InputFD); // initialize read
descriptors
FD_SET(s,&InputFD); // Add
socket to descriptors to
FD_SET(FromDH,&InputFD); // wait on Modem
data as well
FD_ZERO(&wErrorFD);
FD_SET(s,&wErrorFD);
FD_SET(FromDH, &wErrorFD);
signal(SIGALRM,SignalHandler);
while(1){
wInputFD = InputFD;
// don't wait more than 500msec before
reporting
timeout.tv_sec = 0;
timeout.tv_usec = 500000;
short result =
select(FD_SETSIZE,&wInputFD,NULL,&wErrorFD,&timeout);
...
We get a 2 from select, then the pipe (FromDH) indicates
an error. errno is zero. There is no error that we can
see. any clues?
thanks!
