clock_get_time() is a Mach call, so errno isn't relevant:
/usr/include/mach/message.h:#define MACH_SEND_INVALID_DEST
0x10000003
What port did you pass to clock_get_time()?
matt.
p.s. Here's an example of usage:
#include <mach/mach.h>
#include <mach/clock.h>
#include <mach/mach_error.h>
#include <stdio.h>
int main(void) {
kern_return_t ret;
clock_serv_t aClock;
mach_timespec_t aTime;
ret = host_get_clock_service(mach_host_self(), CALENDAR_CLOCK,
&aClock);
if (ret != KERN_SUCCESS) {
fprintf(stderr, "host_get_clock_service() failed: %s\n",
mach_error_string(ret));
abort();
}
ret = clock_get_time(aClock, &aTime);
if (ret != KERN_SUCCESS) {
fprintf(stderr, "clock_get_time() failed: %s\n",
mach_error_string(ret));
abort();
}
printf("aTime = { %u, %u }\n", aTime.tv_sec, aTime.tv_nsec);
return 0;
}
