Manual page for kern_timestamp(2)
kern_timestamp - return (machine-dependent) timestamp
SYNOPSIS
#include <sys/time_stamp.h>
kern_return_t kern_timestamp(struct tsval *tsp)
ARGUMENTS
-
tsp
-
pointer to a struct tsval to receive the timestamp.
DESCRIPTION
kern_timestamp()
obtains a current low-overhead timestamp from the kernel.
DIAGNOSTICS
- KERN_SUCCESS
-
The timestamp has been returned.
- KERN_INVALID_ADDRESS
-
tsp doesn't point to valid user memory.
BUGS
Availability limited. Timestamp format is machine-dependent;
the value
of the symbol
TS_FORMAT
must be saved for
convert_ts_to_tv().
Multimax timestamps are subject to rollover on
an hourly basis (2^32 usec). Timestamps on most other systems have a
granularity of 10ms.
