NAME

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)

CONTENTS

SYNOPSIS

#include <Mrm/MrmPublic.h>
Cardinal MrmRegisterNamesInHierarchy(
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 *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

This function returns one of the following status return constants:
MrmSUCCESS The function executed successfully.
MrmFAILURE The function failed.
