NAME
MrmInitialize -- Prepares an application to use MRM widget-fetching facilities
SYNOPSIS
void MrmInitialize(void)
DESCRIPTION
The MrmInitialize function must be called to prepare an application to use MRM widget-fetching facilities. You must call this function
prior to fetching a widget. However, it is good programming practice to call MrmInitialize prior to performing any MRM operations.
MrmInitialize initializes the internal data structures that MRM needs to successfully perform type conversion on arguments and to success-
fully access widget creation facilities. An application must call MrmInitialize before it uses other MRM functions.

MrmFetchWidget - Fetches and creates any indexed (UIL named) application widgets and its children
SYNOPSIS
#include <Mrm/MrmPublic.h>
Cardinal MrmFetchWidget(hierarchy_id, index, parent_widget, widget, class)
MrmHierarchy hierarchy_id;
String index;
Widget parent_widget;
Widget *widget;
MrmType *class;
DESCRIPTION
The MrmFetchWidget function fetches and creates an indexed application widget and its children. The indexed application widget is any wid-
get that is named in UIL. In fetch operations, the fetched widget's subtree is also fetched and created. This widget must not appear as the
child of a widget within its own subtree. MrmFetchWidget does not execute XtManageChild for the newly created widget. Specifies the ID of
the uid hierarchy that contains the interface definition. The hierarchy_id was returned in a previous call to MrmOpenHierarchyPerDisplay.
Specifies the UIL name of the widget to fetch. Specifies the parent widget ID. Returns the widget ID of the created widget. Returns the
class code identifying MRM's widget class. The widget class code for the main window widget, for example, is MRMwcMainWindow. Literals
identifying MRM widget class codes are defined in <Mrm.h>.
An application can fetch any named widget in the uid hierarchy using MrmFetchWidget. MrmFetchWidget can be called at any time to fetch a
widget that was not fetched at application startup. MrmFetchWidget can be used to defer fetching pop-up widgets until they are first refer-
enced (presumably in a callback), and then used to fetch them once.
MrmFetchWidget can also create multiple instances of a widget (and its subtree). In this case, the uid definition functions as a template;
a widget definition can be fetched any number of times. An application can use this to make multiple instances of a widget, for example, in
a dialog box box or menu.
The index (UIL name) that identifies the widget must be known to the application.
RETURN VALUE
This function returns one of these status return constants: The function executed successfully. The hierarchy ID was invalid. The widget
was not found in UID hierarchy. The function failed.
