okay. i get 87 as a result, which means:
The parameter is incorrect.
now i tried the following:
sub query_users {
my ( $self, $filename ) = @_;
my $func =
import_api( 'advapi32', 'QueryUsersOnEncryptedFile', 'PP', 'N' )
+;
die "Could not import API QueryUsersOnEncryptedFile: $!"
unless defined $func;
$filename = make_unicode( File::Spec->canonpath($filename) );
print "filename: $filename\n";
my $encCertHashList = Win32::API::Struct->new( 'ENCRYPTION_CERTIFI
+CATE_HASH_LIST' );
print "retval: " . $func->Call( $filename, $encCertHashList) . "\n
+";
print $encCertHashList->{nCert_Hash}, "\n";
$encCertHashList = Win32::API::Struct->new( 'ENCRYPTION_CERTIFICAT
+E_HASH_LIST' );
print "retval: " . $func->Call( $filename, \$encCertHashList) . "\
+n";
print $encCertHashList->{nCert_Hash}, "\n";
$encCertHashList = " " x 1024;
print "retval: " . $func->Call( $filename, $encCertHashList) . "\n
+";
print $encCertHashList, "\n";
$encCertHashList = " " x 1024;
print "retval: " . $func->Call( $filename, \$encCertHashList) . "\
+n";
print $encCertHashList, "\n";
}
as a result i get
filename: C : \ e f s . p l
retval: 0

@¤♦
retval: 0
in this case, the call works. but the structure is not really filled.
btw. the file is encrypted!

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).
