Win32::NetResource - manage network resources in perl
=head1 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";
=head1 DESCRIPTION
This module offers control over the network resources of Win32.Disks,
printers etc can be shared over a network.
=head1 DATA TYPES
There are two main data types required to control network resources.
In Perl these are represented by hash types.
=over 10
=item %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.
=back
=item %SHARE_INFO
This hash represents the SHARE_INFO_502 struct.
=over 10
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
=back
=head1 FUNCTIONS
=head2 NOTE
All of the functions return FALSE (0) if they fail.
=over 10
=item GetSharedResources(\@Resources,dwType)
Creates a list in @Resources of %NETRESOURCE hash references.
=item AddConnection(\%NETRESOURCE,$Password,$UserName,$Connection)
Makes a connection to a network resource specified by %NETRESOURCE
=item CancelConnection($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.
=item WNetGetLastError($ErrorCode,$Description,$Name)
Gets the Extended Network Error.
=item GetError( $ErrorCode )
Gets the last Error for a Win32::NetResource call.
=item GetUNCName( $UNCName, $LocalPath );
Returns the UNC name of the disk share connected to $LocalPath in $UNCName.
=head2 NOTE
$servername is optional for all the calls below. (if not given the
local machine is assumed.)
=item NetShareAdd(\%SHARE,$parm_err,$servername = NULL )
Add a share for sharing.
=item NetShareCheck($device,$type,$servername = NULL )
Check if a share is available for connection.
=item NetShareDel( $netname, $servername = NULL )
Remove a share from a machines list of shares.
=item NetShareGetInfo( $netname, \%SHARE,$servername=NULL )
Get the %SHARE_INFO information about the share $netname on the
server $servername.
=item NetShareSetInfo( $netname,\%SHARE,$parm_err,$servername=NULL)
Set the information for share $netname.
