in reply to Getting filehandle access modes on Windows

apparently fcntl on that platform can't be used to determine filehandle access modes.

I wrote Win32::Fmode to address that very problem.

(and syphilis wrapped it over in what he considers a more user-friendly API in FileHandle::Fmode)

Unfortunately, the underlying method used by both requires XS -- that was the only method I could find for gaining access to the information.

I'm not guaranteeing there isn't a non-XS method, but I looked pretty hard at the time and didn't find one.

it uses XS and I'd like something that's pure Perl, as installing XS code on Windows boxes is not something I wish on anyone.

PPM makes it simple. Far simpler than installing pure perl modules on *nix in fact.

A whole 10 seconds (via a very slow connection):

[21:54:11.73] C:\test>ppm install Win32::Fmode Downloading Win32-Fmode-1.0.6...done Unpacking Win32-Fmode-1.0.6...done Generating HTML for Win32-Fmode-1.0.6...done Updating files in site area...done 6 files installed [21:54:20.57] C:\test>

    Thanks! I missed that. All I found was Win32API::File, which exposes file attributes, but not the filehandle ones.

    Good to know. I won't shy away from using XS then.

    Thanks again.
