BSD::Itimer allows you to access the interval timer many Unix systems provide without resorting to non-portable syscalls. This is version 0.8. It has a very simple functional interface to the get/setitimer functions. Suggestions or code implementing a nicer interface welcome; I can be reached as hag@linnaean.org . BSD::Itimer is available from my home page, http://www.linnaean.org/~hag/ , and your nearest CPAN mirror in CPAN/authors/id/H/HA/HAG. Version 0.8 has been tested on: Linux 2.0.36 NetBSD 1.4 FreeBSD 2.2.6 SunOS 4.1.4 Solaris 2.6 IRIX 6.5 OSF/1 4.0 HPUX 10.10
