posix requires that EINVAL be returned if the first parameter specifies
the cpu-time clock of the calling thread (CLOCK_THREAD_CPUTIME_ID).
linux returns ENOTSUP instead so we handle this.
#include <time.h>
+#include <errno.h>
#include "syscall.h"
#include "libc.h"
int clock_nanosleep(clockid_t clk, int flags, const struct timespec *req, struct timespec *rem)
{
- return -__syscall_cp(SYS_clock_nanosleep, clk, flags, req, rem);
+ int r = -__syscall_cp(SYS_clock_nanosleep, clk, flags, req, rem);
+ return clk == CLOCK_THREAD_CPUTIME_ID ? EINVAL : r;
}
