SYNOPSIS

    use Win32::NetResource;

    $ShareInfo = {
                    'path' => "C:\\MyShareDir",
                    'netname' => "MyShare",
                    'remark' => "It is good to share",

                    '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 (0) if they fail.

GetSharedResources(\@Resources,dwType)

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.

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.

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 share is available for connection.

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

    #
    # 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 $err = undef;
        GetError($err);
        warn Win32::FormatMessage($err);
    }

    foreach my $href (@$resources) {
        next if ($$href{DisplayType} != RESOURCEDISPLAYTYPE_SHARE);
        print "-----\n";
        foreach( keys %$href){
            print "$_: $href->{$_}\n";
        }
    }
