Subject: [PATCH] linux-user: remove host stime() syscall
stime() has been withdrawn from glibc
(12cbde1dae6f "Use clock_settime to implement stime; withdraw stime.")
Implement the target stime() syscall using host
clock_settime(CLOCK_REALTIME, ...) as it is done internally in glibc.
Tested qemu-ppc/x86_64 with:
#include <time.h>
#include <stdio.h>
int main(void)
{
time_t t;
int ret;
/* date -u -d"2019-11-12T15:11:00" "+%s" */
t = 1573571460;
ret = stime(&t);
printf("ret %d\n", ret);
return 0;
}
# date; ./stime; date
Tue Nov 12 14:18:32 UTC 2019
ret 0
