Hi Waldemar,
The following snippet should do it when compiled statically for MIPS32
and emulated using qemu-user-static:
#include <time.h>
#include <stddef.h>
#include <unistd.h>
int main(int argc, char **argv) {
time_t start = time(NULL);
sleep(2);
time_t end = time(NULL);
return end != start;
}
When I strace the resulting binary, I saw:
[pid 2271212] rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
[pid 2271212] clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=0, tv_nsec=2},
0x7ffca592a250) = 0
[pid 2271212] brk(0x611d0d49b000) = 0x611d0d49b000
[pid 2271212] exit_group(1) = ?
But I expected to see:
[pid 2271212] rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
[pid 2271212] clock_nanosleep(CLOCK_REALTIME, 0, {tv_sec=2, tv_nsec=0},
0x7ffca592a250) = 0
[pid 2271212] brk(0x611d0d49b000) = 0x611d0d49b000
[pid 2271212] exit_group(1) = ?
kind regards
Nadav
