Revision history for Perl extension Time::HiRes.
+1.38
+ - no functional changes
+ - move lib/Time/HiRes.pm as Hires.pm
+ - libraries scanning was slightly broken (always scanned
+ for a library even when $Config{libs} already had it)
+
+1.37
+ - Ray Zimmerman ran into a race condition in Mac OS X.
+ A 0.01-second alarm fired before the test expected.
+ The test first slept indefinitely (blocking for signals)
+ and only after that tested for the signal having been sent.
+ Since the signal had already been sent, the test #12 never
+ completed. The solution: test first, then block.
+ - default to being silent on all probing attempts, set the
+ environment variable VERBOSE to a true value to see the
+ details (the probing command and the possible errors)
+
+1.36
+ - do not clear MAN3PODS in Makefile.PL (Radoslaw Zielinski)
+ - INSTALLDIRS => 'perl' missing which means that Time::HiRes
+ cannot be upgraded from CPAN to override the 5.8.0 version
+ (Guido A. Ostkamp)
+ - Time::HiRes 1.35 could not be dropped as-is to bleadperl
+ because the include directories did not adjust themselves
+ if $ENV{PERL_CORE} (Hugo van der Sanden)
+ - add documentation about the restart of select() under alarm()
+
+1.35
+ - small documentation tweaks
+
+
+1.34
+ - better VMS operation (Craig Berry)
+
+1.33
+ - our time machine is accelerating: now works with Perl 5.004_01
+ (tried with 5.003_07 and 5.002 but I get segmentation faults
+ from running the Makefile.PL with those in Tru64 4.0D)
+
+1.32
+ - backward compatibility (pre-5.6.0) tweaks:
+ - no XSLoader in 5.00503, use DynaLoader instead
+ - no SvPV_nolen, either
+ - no PerlProc_pause(), either
+ - now tested with 5.00404 and 5.00503
+ - Makefile.PL requires 5.00404 (no more 5.002)
+ - use nanosleep instead of usleep, if it is available (Wilson Snyder)
+ (this means that one can mix subsecond sleeps with alarms)
+ - because of nanosleep we probe for -lrt and -lposix4
+ - the existence of getitimer/nanosleep/setitimer/ualarm/usleep
+ is available by exportable constants Time::HiRes::d_func
+ (since older Perl do not have them in %Config, and even
+ 5.8.0 does not probe for nanosleep)
+
+1.31
+ - backward compatibility (pre-5.6.1) tweaks:
+ - define NV if no NVTYPE
+ - define IVdf if needed (note: the Devel::PPPort
+ in 5.8.0 does not try hard hard enough since
+ the IVSIZE might not be defined)
+ - define NVgf if needed
+ - grab the typemap from 5.8.0 for the NV stuff
+1.30
+
+ - release 1.29_02 as 1.30
+
+1.29_02
+
+ - fix a silly unclosed comment typo in HiRes.xs
+ - document and export REALTIME_REALPROF (Solaris)
+
+1.29_01
+
+ - only getitimer(ITIMER_REAL) available in Cygwin and Win32
+ (need to patch this also in Perl 5.[89])
+ - remove CVS revision log from HiRes.xs
+
+1.29_00

+ you can browse them at http://public.activestate.com/cgi-bin/perlbrowse

The C<Time::HiRes> module implements a Perl interface to the usleep,
ualarm, gettimeofday, and setitimer/getitimer system calls. See the
EXAMPLES section below and the test scripts for usage; see your system
-documentation for the description of the underlying usleep, ualarm,
-gettimeofday, and setitimer/getitimer calls.
+documentation for the description of the underlying nanosleep or usleep,
+ualarm, gettimeofday, and setitimer/getitimer calls.
If your system lacks gettimeofday(2) or an emulation of it you don't
-get gettimeofday() or the one-arg form of tv_interval().
-If you don't have usleep(3) or select(2) you don't get usleep()
+get gettimeofday() or the one-arg form of tv_interval(). If you don't
+have nanosleep() or usleep(3) or select(2) you don't get Time::HiRes::usleep()
or sleep(). If your system don't have ualarm(3) or setitimer(2) you
-don't get ualarm() or alarm(). If you try to import an unimplemented
-function in the C<use> statement it will fail at compile time.
+don't get Time::HiRes::ualarm() or alarm().
+
+If you try to import an unimplemented function in the C<use> statement
+it will fail at compile time.
+
+If your subsecond sleeping is implemented with nanosleep() instead of
+usleep(), you can mix subsecond sleeping with signals since
+nanosleep() does not use signals. This, however, is unportable
+behavior, and you should first check for the truth value of
+C<&Time::HiRes::d_nanosleep> to see whether you have nanosleep,
+and then read carefully your nanosleep() C API documentation for
+any peculiarities. (There is no separate interface to call nanosleep();
+just use Time::HiRes::sleep() or usleep() with small enough values. Also,
+think twice whether using nanosecond accuracies in a Perl program is what
+you should be doing.)
The following functions can be imported from this module.
No functions are exported by default.
=item alarm ( $floating_seconds [, $interval_floating_seconds ] )
-The SIGALRM signal is sent after the specfified number of seconds.
+The SIGALRM signal is sent after the specified number of seconds.
Implemented using ualarm(). The $interval_floating_seconds argument
is optional and will be 0 if unspecified, resulting in alarm()-like
behaviour. This function can be imported, resulting in a nice drop-in
replacement for the C<alarm> provided with perl, see the EXAMPLES below.
+B<NOTE 1>: With some platform - Perl release combinations select()
+gets restarted by SIGALRM, instead of dropping out of select().
+This means that an alarm() followed by a select() may together take
+the sum of the times specified for the the alarm() and the select(),
+not just the time of the alarm().
+
=item setitimer
C<setitimer ( $which, $floating_seconds [, $interval_floating_seconds ] )>
In list context, both the remaining time and the interval are returned.
-There are three interval timers: the $which can be ITIMER_REAL,
-ITIMER_VIRTUAL, or ITIMER_PROF.
+There are usually three or four interval timers available: the $which
+can be ITIMER_REAL, ITIMER_VIRTUAL, ITIMER_PROF, or ITIMER_REALPROF.
+Note that which ones are available depends: true UNIX platforms have
+usually all first three, but for example Win32 and Cygwin only have
+ITIMER_REAL, and only Solaris seems to have ITIMER_REALPROF (which is
+used to profile multithreaded programs).
ITIMER_REAL results in alarm()-like behavior. Time is counted in
I<real time>, that is, wallclock time. SIGALRM is delivered when
