NAME
----
zclock - millisecond clocks and delays
SYNOPSIS
--------
----
// Sleep for a number of milliseconds
CZMQ_EXPORT void
zclock_sleep (int msecs);
// Return current system clock as milliseconds
CZMQ_EXPORT int64_t
zclock_time (void);
// Print formatted string to stdout, prefixed by date/time and
// terminated with a newline.
CZMQ_EXPORT void
zclock_log (const char *format, ...);
// Return formatted date/time as fresh string.
CZMQ_EXPORT char *
zclock_timestr (void);
// Self test of this class
CZMQ_EXPORT int
zclock_test (bool verbose);
----
DESCRIPTION
-----------
The zclock class provides essential sleep and system time functions, used
to slow down threads for testing, and calculate timers for polling. Wraps
the non-portable system calls in a simple portable API.
The Win32 Sleep() call defaults to 16ms resolution unless the system timer
resolution is increased with a call to timeBeginPeriod() permitting 1ms
granularity.
EXAMPLE
-------
.From zclock_test method
----
int64_t start = zclock_time ();
zclock_sleep (10);
assert ((zclock_time () - start) >= 10);
char *timestr = zclock_timestr ();
if (verbose)
puts (timestr);
free (timestr);
