/*
* dragdrop.c -
*
* Code for Drag/Drop API's.
*
* This code assumes something else does all the dragging work; it just
* takes a list of files after all the extra stuff.
*
* The File Manager is responsible for doing the drag loop, determining
* what files will be dropped, formatting the file list, and posting
* the WM_DROPFILES message.
*
* The list of files is a sequence of zero terminated filenames, fully
* qualified, ended by an empty name (double NUL). The memory is allocated
* DDESHARE.
