Function UpdateRecentArray

src/drivers/win/window.cpp:703–759

Helper function to populate the recent directories and recent files arrays. @param addString String to add to the array. @param bufferArray Array where the string will be added. @param arrayLen Length of the bufferArray. @param menu Menu handle of the main menu. @param menuItem @param baseID
