## Name

MrmRegisterNamesInHierarchy(3X) — MrmRegisterNamesInHierarchy--Registers the values associated with the names referenced in UIL within a single hierarchy (for example, UIL callback function names or UIL identifier names) MrmRegisterNamesInHierarchyuil functions

## Synopsis

#include <Mrm/MrmPublic.h>
Cardinal MrmRegisterNamesInHierarchy(`hierarchy_id, register_list, register_count`)
MrmHierarchy `hierarchy_id`;
MrmRegisterArglist `register_list`;
MrmCount `register_count`;

## DESCRIPTION

The MrmRegisterNamesInHierarchy function registers a vector of names and associated values for access in MRM. The values can be callback functions, pointers to user-defined data, or any other values. The information provided is used to resolve symbolic references occurring in UID files to their run-time values.For callbacks, this information provides the procedure address required by the Motif Toolkit. For names used as identifiers in UIL, this information provides any run-time mapping the application needs.

This function is similar to MrmRegisterNames, except that the scope of the names registered by MrmRegisterNamesInHierarchy is limited to the hierarchy specified by `hierarchy_id`, whereas the names registered by MrmRegisterNames have global scope. When MRM looks up a name, it first tries to find the name among those registered for the given hierarchy. If that lookup fails, it tries to find the name among those registered globally.

`hierarchy_id` |  | Specifies the hierarchy with which the names are to be associated.
`register_list` |  | Specifies a list of name/value pairs for the names to be registered. Each name is a case-sensitive, NULL-terminated ASCII string. Each value is a 32-bit quantity, interpreted as a procedure address if the name is a callback function, and uninterpreted otherwise.
`register_count` |  | Specifies the number of entries in `register_list`.

The names in the list are case-sensitive. The list can be either ordered or unordered.

Callback functions registered through MrmRegisterNamesInHierarchy can be either regular or creation callbacks. Regular callbacks have declarations determined by Motif Toolkit and user requirements. Creation callbacks have the same format as any other callback:

    void CallBackProc(widget_id, tag, callback_data)

       Widget   *widget_id;

       Opaque   tag;

       XmAnyCallbackStruct   *callback_data;

`widget_id` |  | Specifies the widget ID associated with the widget performing the callback (as in any callback function).
`tag` |  | Specifies the tag value (as in any callback function).
`callback_data` |  | Specifies a widget-specific data structure. This data structure has a minimum of two members: event and reason. The reason member is always set to MrmCR_CREATE.

Note that the widget name and parent are available from the widget record accessible through `widget_id`.

## RETURN VALUE

This function returns one of these status return constants:

MrmSUCCESS |  | The function executed successfully.
MrmFAILURE |  | The function failed.
