NAME
       DtWsmAddWorkspaceModifiedCallback -- add a callback to be called when any workspace is changed

SYNOPSIS
       #include <Dt/Wsm.h>
       DtWsmCBContext DtWsmAddWorkspaceModifiedCallback(
       Widget widget,
       DtWsmWsModifiedProc ws_change,
       Pointer client_data);

DESCRIPTION
       The  DtWsmAddWorkspaceModifiedCallback function works with the CDE workspace manager, dtwm(1), and registers a function to be called when a
       workspace is added, deleted or modified.

       The widget argument is a realized widget.

       The ws_change argument is the procedure to be called when a workspace is modified.

       The client_data argument points to arbitrary client data to be passed back to ws_change.

       The header defines the DtWsmWsModifiedProc callback prototype as follows:

       typedef void (*DtWsmWsModifiedProc)(Widget widget,
	       Atom aWorkspace,
	       DtWsmWsReason reason,
	       Pointer client_data);

       The widget argument is the ID of the widget to be registered with the callback.

       The aWorkspace argument is the name of the new current workspace (converted to an X atom).

       The reason argument is a type of modification:

       DtWSM_REASON_ADD
		 A new workspace was added.

       DtWSM_REASON_BACKDROP
		 The backdrop for the workspace changed.

       DtWSM_REASON_CURRENT
		 A different workspace was made the current workspace.

       DtWSM_REASON_DELETE
		 A workspace was deleted.

       DtWSM_REASON_TITLE
		 The workspace title changed.

       The client_data argument points to the client data to be registered with the callback.

RETURN VALUE
       Upon successful completion, the DtWsmAddWorkspaceModifiedCallback function returns a workspace callback registration context.

APPLICATION USAGE
       The DtWsmAddWorkspaceModifiedCallback function returns a registration context that the application must save in order to remove this  call-
       back later.

       DtWsmAddWorkspaceModifiedCallback requires a window; thus, a gadget is not acceptable for the widget argument.

       The DtWsmRemoveWorkspaceCallback(3) function needs a registration context to remove the callback.
