- 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- stime() has been withdrawn from glibc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
- Tue Nov 12 15:11:00 UTC 2019
- Upstream-Status: Backport [https://git.qemu.org/?p=qemu.git;a=commit;h=0f1f2d4596aee037d3ccbcf10592466daa54107f]
