DESCRIPTION

The MrmRegisterNames function 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 MrmRegisterNamesInHierarchy, except that the scope of the names registered by MrmRegisterNamesInHierarchy is limited to the hierarchy specified in the call to that function, 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.

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 MrmRegisterNames 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_idOpaque
tagXmAnyCallbackStruct
*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.
