* 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.
