Time::HiRes module: High resolution time, sleep, and alarm. Implement usleep, ualarm, and gettimeofday for Perl, as well as wrappers to implement time, sleep, and alarm that know about non-integral seconds. Note that your underlying operating system must have the usleep(), ualarm(), and gettimeofday() routines, or you will get "Undefined externals" messages when building or testing this. I *may* be able to help in this case, see the documentation. POD documentation is embedded. Copyright (c) 1996 Douglas E. Wegscheid. All rights reserved.
