Compare
A plugin can export the function Compare to override the default file panel sorting
algorithm.
int WINAPI Compare( HANDLE hPlugin, const struct PluginPanelItem *Item1, const struct PluginPanelItem *Item2, unsigned int Mode );
Parameters
hPlugin
Plugin handle, returned by OpenPlugin
or OpenFilePlugin.
Item1, Item2
Pointers to PluginPanelItem
structures to compare.
Mode
See Sort modes
Return value
This function returns an int value that is:
-1
if Item1 <
Item2
0
if Item1 ==
Item2
1
if Item1 >
Item2
-2
if the default FAR compare function should be used for this sort mode.
Remarks
The standard RTL qsort function that implements and unstable sorting algorithm
is used by FAR for sorting needs. In other words if array elements are equal to the compare
function then on the panels they will be shown in random order, that changes upon each
redrawing of the panel.
