Name
Overlapped
Synopsis
This class encapsulates the Win32 API OVERLAPPED
structure. NativeOverlapped
is needed to
mimic the structure the API expects, but this class encapsulates the overlapped
structure into a .NET class. You can create NativeOverlapped
structures by
calling Pack()
, and
create Overlapped
objects with
the static Unpack()
method. To avoid a memory leak, each NativeOverlapped
that you create must also be freed by calling the
static Free()
method. Unpack()
does
not free the memory.
