// OPostponedTruncationFileStream
|
|
//
|
|
// Allows to get stream access to a file, where the first truncation
|
|
// of the file is postponed till the first writing. If no writing happens
|
|
// after the first truncation/creation, it has no effect. ( The postponing of
|
|
// the creation can be switched off during initialization. Here the postponing
|
|
// of the creation means that the file will be created immediatelly, but
|
|
// if nothing is written into it, it will be removed during destruction
|
|
// of the object. )
|
|
//
|
|
// On creation of this object the target file is scheduled for
|
|
// creation/truncation. But the action happens only during the first
|
|
// write access. After the first write access the object behaves
|
|
// itself as the original stream.
