DwtRegisterDRMNames(3Dwt) DwtRegisterDRMNames(3Dwt)
Name
DwtRegisterDRMNames - Registers the values associated with the names referenced in UIL (for example, UIL callback function names or UIL
identifier names).
Syntax
#include <X11/DwtAppl.h>
Cardinal DwtRegisterDRMNames(register_list, register_count)
DRMRegisterArglist register_list;
DRMCount register_count;
Arguments
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 uninter-
preted otherwise.
register_count
Specifies the number of entries in register_list.
Description
The DwtRegisterDRMNames function registers a vector of names and associated values for access in DRM. The values can be callback func-
tions, 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 XUI Toolkit. For names
used as identifiers in UIL, this information provides any run-time mapping the application needs.
The names in the list are case-sensitive. The list can be either ordered or unordered.
Callback functions registered through DwtRegisterDRMNames can be either regular or creation callbacks. Regular callbacks have declarations
determined by XUI 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;
DwtAnyCallbackStruct *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 mem-
ber is always set to DwtCRCreate.
Note that the widget name and parent are available from the widget record accessible through widget_id.
Return Values
This function returns one of these status return constants:
DRMSuccess The function executed
successfully.
DRMFailure Memory allocation failed.
