NAME ^

Win32::NetResource - Manage network resources in Perl

SYNOPSIS ^

    use Win32::NetResource;

    $ShareInfo = {
                    'path' => "C:\\MyShareDir",
                    'netname' => "MyShare",
                    'remark' => "It is good to share",
                    'passwd' => "",
                    'current-users' =>0,
                    'permissions' => 0,
                    'maxusers' => -1,
                    'type'  => 0,
                    };
    
    Win32::NetResource::NetShareAdd( $ShareInfo,$parm )
        or die "unable to add share";

DESCRIPTION ^

This module offers control over the network resources of Win32.Disks, printers etc can be shared over a network.

DATA TYPES ^

There are two main data types required to control network resources. In Perl these are represented by hash types.

%NETRESOURCE
    KEY                    VALUE
    
    'Scope'         =>  Scope of an Enumeration
                        RESOURCE_CONNECTED,
                        RESOURCE_GLOBALNET,
                        RESOURCE_REMEMBERED.
    
    'Type'          =>  The type of resource to Enum
                        RESOURCETYPE_ANY    All resources
                        RESOURCETYPE_DISK    Disk resources
                        RESOURCETYPE_PRINT    Print resources
    
    'DisplayType'   =>  The way the resource should be displayed.
                        RESOURCEDISPLAYTYPE_DOMAIN    
                        The object should be displayed as a domain.
                        RESOURCEDISPLAYTYPE_GENERIC    
                        The method used to display the object does not matter.
                        RESOURCEDISPLAYTYPE_SERVER    
                        The object should be displayed as a server.
                        RESOURCEDISPLAYTYPE_SHARE    
                        The object should be displayed as a sharepoint.
    
    'Usage'         =>  Specifies the Resources usage:
                        RESOURCEUSAGE_CONNECTABLE
                        RESOURCEUSAGE_CONTAINER.
    
    'LocalName'     =>  Name of the local device the resource is 
                        connected to.
    
    'RemoteName'    =>  The network name of the resource.
    
    'Comment'       =>  A string comment.
    
    'Provider'      =>  Name of the provider of the resource.
%SHARE_INFO

This hash represents the SHARE_INFO_502 struct.

    KEY                    VALUE
    'netname'        =>    Name of the share.
    'type'           =>    type of share.
    'remark'         =>    A string comment.
    'permissions'    =>    Permissions value
    'maxusers'       =>    the max # of users.
    'current-users'  =>    the current # of users.
    'path'           =>    The path of the share.
    'passwd'         =>    A password if one is req'd

FUNCTIONS ^

NOTE

All of the functions return false if they fail.

GetSharedResources(\@Resources,dwType,\%NetResource = NULL)

Creates a list in @Resources of %NETRESOURCE hash references.

The return value indicates whether there was an error in accessing any of the shared resources. All the shared resources that were encountered (until the point of an error, if any) are pushed into @Resources as references to %NETRESOURCE hashes. See example below. The \%NetResource argument is optional. If it is not supplied, the root (that is, the topmost container) of the network is assumed, and all network resources available from the toplevel container will be enumerated.

AddConnection(\%NETRESOURCE,$Password,$UserName,$Connection)

Makes a connection to a network resource specified by %NETRESOURCE

CancelConnection($Name,$Connection,$Force)

Cancels a connection to a network resource connected to local device $name.$Connection is either 1 - persistent connection or 0, non-persistent.

WNetGetLastError($ErrorCode,$Description,$Name)

Gets the Extended Network Error.

GetError( $ErrorCode )

Gets the last Error for a Win32::NetResource call.

GetUNCName( $UNCName, $LocalPath );

Returns the UNC name of the disk share connected to $LocalPath in $UNCName. $LocalPath should be a drive based path. e.g. "C:\\share\\subdir"

NOTE

$servername is optional for all the calls below. (if not given the local machine is assumed.)

NetShareAdd(\%SHARE,$parm_err,$servername = NULL )

Add a share for sharing.

NetShareCheck($device,$type,$servername = NULL )

Check if a directory or a device is available for connection from the network through a share. This includes all directories that are reachable through a shared directory or device, meaning that if C:\foo is shared, C:\foo\bar is also available for sharing. This means that this function is pretty useless, given that by default every disk volume has an administrative share such as "C$" associated with its root directory.

$device must be a drive name, directory, or a device. For example, "C:", "C:\dir", "LPT1", "D$", "IPC$" are all valid as the $device argument. $type is an output argument that will be set to one of the following constants that describe the type of share:

    STYPE_DISKTREE     Disk drive 
    STYPE_PRINTQ       Print queue 
    STYPE_DEVICE       Communication device 
    STYPE_IPC          Interprocess communication (IPC) 
    STYPE_SPECIAL      Special share reserved for interprocess
                         communication (IPC$) or remote administration
                         of the server (ADMIN$). Can also refer to
                         administrative shares such as C$, D$, etc.
NetShareDel( $netname, $servername = NULL )

Remove a share from a machines list of shares.

NetShareGetInfo( $netname, \%SHARE,$servername=NULL )

Get the %SHARE_INFO information about the share $netname on the server $servername.

NetShareSetInfo( $netname,\%SHARE,$parm_err,$servername=NULL)

Set the information for share $netname.

EXAMPLE ^

Enumerating all resources on the network
    #
    # This example displays all the share points in the entire
    # visible part of the network.
    #

    use strict;
    use Win32::NetResource qw(:DEFAULT GetSharedResources GetError);
    my $resources = [];
    unless(GetSharedResources($resources, RESOURCETYPE_ANY)) {
        my $err;
        GetError($err);
        warn Win32::FormatMessage($err);
    }

    foreach my $href (@$resources) {
        next if ($$href{DisplayType} != RESOURCEDISPLAYTYPE_SHARE);
        print "-----\n";
        foreach( keys %$href){
            print "$_: $href->{$_}\n";
        }
    }
Enumerating all resources on a particular host
    #
    # This example displays all the share points exported by the local
    # host.
    #

    use strict;
    use Win32::NetResource qw(:DEFAULT GetSharedResources GetError);
    if (GetSharedResources(my $resources, RESOURCETYPE_ANY,
                           { RemoteName => "\\\\" . Win32::NodeName() }))
    {
        foreach my $href (@$resources) {
            print "-----\n";
            foreach(keys %$href) { print "$_: $href->{$_}\n"; }
        }
    }
