getclock - Get current value of system-wide clock
struct timespec *tp );
Standard C Library (libc)
Identifies a system-wide clock. Points to a timespec
structure space where the current value of the system-wide
clock is stored.
The getclock() function sets the current value of the
clock specified by clktyp into the location pointed to by
the tp parameter.
The clktyp parameter is given as a symbolic constant name,
as defined in the sys/timers.h include file. Only the
TIMEOFDAY symbolic constant, which specifies the normal
time-of-day clock to access for system-wide time, is supported.
For the clock specified by TIMEOFDAY, the value returned
by this function is the elapsed time since the epoch. The
epoch is referenced to 00:00:00 UTC (Coordinated Universal
Time) 1 Jan 1970.
The getclock() function returns a timespec structure,
which is defined in the sys/timers.h header file. It has
the following members:
