"missing" perl routines

kschwab has asked for the wisdom of the Perl Monks concerning the following question:

Over time, I've happened upon two common unix routines that are missing in Perl. The two I've run into are setgroups() and lchmod().

Am I just not looking in the right spot ? Also, are there any other common routines other folks have noticed missing ?

For setgroups see GID in perlvar. If lchmod (UPDATE: yup) is what I think it is it's nearly pointless no? The permissions on the destination conrtol acccess. `-- I'm not belgian but I play one on TV.`	[reply]

As for lchmod, yes, I see your point. But what if I were trying to rewrite something like tar ? It wouldn't matter a lot, but it wouldn't work just like the C implementation.	[reply]

Then you would write a module in C to implement `lchmod`, and `use` it in your program.	[reply] [d/l]
