In theory, this should work...but it doesn't.

#! perl -slw use strict; use Encode; use Devel::Peek; use Win32::API::Prototype; ApiLink( 'advapi32', q[ DWORD QueryUsersOnEncryptedFile( LPCWSTR lpFileName, ULONG pUsers ) ]) or die $^E; my $buffer = chr(0) x 4; print Dump( $buffer ); my $pointer = unpack 'L!', pack 'P', $buffer; printf "%08x\n", $pointer; my $uFile = encode( 'UTF-16LE', $_ = $ARGV[ 0 ], 1 ); print $uFile; QueryUsersOnEncryptedFile( $uFile, $pointer ) or die "$! : $^E"; print Dump( \$buffer ); print unpack 'C*',$buffer;

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
