DXmSvnGetDisplayed - Retrieves (returns) displayed entry numbers and related information necessary to draw a corresponding display.
The identifier (widget ID) of the SVN widget.
A pointer to an array of integers to receive the entry numbers
of the entries being displayed.
A pointer to an array of longwords to receive the application's
value for each entry displayed. If tags are not required,
a Null pointer may be passed.
A pointer to an array of longwords to receive the
coordinates for each entry displayed. If
coordinates are not required, a Null pointer can be passed.
The number of entries allocated in the provided array.
The DXmSvnGetDisplayed routine returns information about the entries that the SVN widget is currently displaying. This information can then be used to keep a simultaneous display up to date with the SVN widget window (in the case of a dialog box, for example, which might contain totals for the entries being displayed).
The application is responsible for managing the memory used to return this list of entries. As such, note the following: At the minimum, the number of entries in the array should be capable of holding at least the number of entries indicated by the value returned from the DXmSvnGetNumDisplayed routine. If there are more entries in the array than the application will need, the SVN widget will set the value for those extra entries to 0. If the capacity of the arrays passed is less than the number of selected entries, only the number of entries allocated in the provided array (the value for len) will be returned.
