UnlockRegion method

Project: Stream Extension Classes

Unit: PJIStreams

Classes: TPJIStreamWrapper, TPJHandleIStreamWrapper, TPJFileIStream

Applies to: ~>3.0

function UnlockRegion(libOffset: Largeint; cb: Largeint;
  dwLockType: Longint): HResult; virtual; stdcall;


Does nothing.

This method may remove the access restriction on a range of bytes previously restricted with LockRegion. It is optional whether support is provided for region locking – this implementation does not do so. A do-nothing stub method is provided that returns the value required by the Microsoft documentation.
