-/**
- Delete file which is possibly not closed.
-
- This function is intended to be used exclusively as a temporal solution
- for Win NT in case when it is needed to delete a not closed file (note
- that the file must be opened everywhere with FILE_SHARE_DELETE mode).
- Deleting not-closed files can not be supported on Win 98|ME (and because
- of that is considered harmful).
-
- The function deletes the file with its preliminary renaming. This is
- because when not-closed share-delete file is deleted it still lives on
- a disk until it will not be closed everwhere. This may conflict with an
- attempt to create a new file with the same name. The deleted file is
- renamed to <name>.<num>.deleted where <name> - the initial name of the
- file, <num> - a hexadecimal number chosen to make the temporal name to
- be unique.
-
- @param the name of the being deleted file
- @param the flags instructing how to react on an error internally in
- the function
-
- @note The per-thread @c my_errno holds additional info for a caller to
- decide how critical the error can be.
-
- @retval
- 0 ok
- @retval
- 1 error
