Hello!
I am having trouble using {g,s}etsockopt(SO_RCVTIMEO). Consider the following
small test program.
I expect to retrieve the value of 1 second via getsockopt call, I expect the
following output:
tv_sec=1, tv_usec=0
But I actually get
tv_sec=0, tv_usec=0
What am I missing?
Thanks!
PS: on Linux it works as I expect.
#include <err.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <sys/time.h>
int main() {
struct timeval tv;
int fd;
tv.tv_sec=1;
tv.tv_usec=0;
fd = socket(PF_UNIX, SOCK_STREAM, 0);
if (fd < 0)
err(1, "socket");
socklen_t len = sizeof(struct timeval);
if (setsockopt(fd, SOL_SOCKET, SO_RCVTIMEO, &tv, len))
err(1, "setsockopt");
if (getsockopt(fd, SOL_SOCKET, SO_RCVTIMEO, &tv, &len))
err(1, "getsockopt");
printf("tv_sec=%ld, tv_usec=%ld\n", tv.tv_sec, tv.tv_usec);
}
