File handles are created with `CreateFile`. Mind you, Win32API::File's `GetOsFHandle` will return the system handle for a given Perl file handle.	[reply] [d/l] [select]

If i use Win32::File to create a file handle, Perl complain about can't packetize So i created a struct like the example becouse the dll was made with visual c++ and appear work `Win32::API::Struct->typedef( 'HANDLE', qw( LPCTSTR lpFileName; DWORD dwDesiredAccess; DWORD dwShareMode; LPSECURITY_ATTRIBUTES lpSecurityAttributes; DWORD dwCreationDisposition; DWORD dwFlagsAndAttributes; HANDLE hTemplateFile; )); my $handle = Win32::API::Struct->new( 'HANDLE' );` [download] Unfortunately without documentation, i receive a Dll Runtime Error, so i guest that i missed other parameter but this's another history Thank and Merry Christmas	[reply] [d/l]

You seem to be completely misunderstanding the nature of a handle. A handle is an opaque identifier (32-bit number) given to you by the system in response to a request that allocates a system resource. You can't just make one up, because the associated resource would be missing.	[reply]

What are you trying to do? See http://cpansearch.perl.org/src/COSIMO/Win32-API-0.59/t/03_undef.t instead of GetOsFHandle you can use fileno	[reply]

Backwards. `GetOsFHandle` returns the file handle. `fileno` is returns a C lib emulation of unix file descriptors.	[reply] [d/l] [select]

I'm trying of load and use a dll on Perl, the function itself needed a struct of file handle because read a file and pass it to it, that was a good point to start. Thank	[reply]
