The simple test I wrote is:
#include <stdio.h>
#include <errno.h>
#include <string.h>
#include <limits.h>
#include <sys/select.h>
#include <sys/time.h>
int main(int argc, char **argv)
{
fd_set set;
FD_ZERO(&set);
struct timeval tv;
tv.tv_sec = INT_MAX;
tv.tv_usec = 0;
FD_SET(0, &set);
int ret = select(1, &set, &set, &set, &tv);
printf("Result %d: %s\n", ret, strerror(errno));
printf("time_t: %lu suseconds_t: %lu\n", sizeof(time_t),
sizeof(suseconds_t));
return 0;
}
This exits with EINVAL for me on OSX, if I replace INT_MAX with 1000, it runs
just fine. The man page on OSX mentions EINVAL for values that exceed the
maximum timeout, so it looks like OSX is not following the spec, then...
Cheers,
Merijn
