The stupid question is the question not asked

The getpwnam function is unimplemented (in Windows)

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

Hi, I've been given a perl program that a colleague runs perfectly well on unix. It says it's fine to run on windows but I get the following error:

The getpwnam function is unimplemented

I've done a bit of searching and it seems that getpwnam isn't implemented with ActivePerl.

Another website said that the equivalent of getpwnam on windows is NetUserGetInfo(). Is this correct or is there a way I can get getpwnam?

    use Win32; my $userName = Win32::LoginName(); print "Current User: ", $userName, "\n";

    It's hard to say what the correct way is. getpwnam returns the password structure (and that's different things on different *Nixes but basically user name, user id, group id, encrypted password, real name, home directory, and shell). Exactly what do you need for your script?


      The only place it's called is in the following subroutine:

      sub map_user_group { if( ! defined( $uid ) ){ if( $user =~ /^\d+$/ ){ # User is just a number - presume it is the uid $uid = $user; } else { $uid = (getpwnam( $user ))[ 2 ]; } } if( ! defined( $gid ) ){ if( $group =~ /\d+$/ ){ # Group is just a number - presume it is the gid $gid = $group; } else { $gid = (getgrnam( $group ))[ 2 ]; } } }

      Any ideas would be much appreciated!

        that snippet of code sets the userid and groupid ... concepts that are foreign to a lot of windows systems. It's not so much that ActivePerl doesn't implement getpwnam (and getgrnam) but that there's no need for it on a windows platform. Exactly what is the script doing with $uid and $gid?

      I'm afraid that that isn't going to help being, as it says on the tin, a " by-name interface to Perl's built-in getpw*() functions".

      I think making a wrapper round some Win32::* modules method so it has the same interface as getpwnam() will be the way to go.
