WSAOVERLAPPED (Windows CE 5.0)

Send Feedback

This structure provides a communication medium between the initiation of an overlapped I/O operation and its subsequent completion.

typedef struct _WSAOVERLAPPED {DWORD Internal;DWORD InternalHigh;DWORD Offset;DWORD OffsetHigh;WSAEVENT hEvent;} WSAOVERLAPPED, *LPWSAOVERLAPPED;

Members

  • Internal
    Reserved for internal use. The Internal member is used internally by the entity that implements overlapped I/O. For service providers that create sockets as installable file system (IFS) handles, this parameter is used by the underlying operating system. Other service providers (non-IFS providers) are free to use this parameter as necessary.
  • InternalHigh
    Reserved. Used internally by the entity that implements overlapped I/O. For service providers that create sockets as IFS handles, this parameter is used by the underlying operating system. Non-IFS providers are free to use this parameter as necessary.
  • Offset
    Reserved for use by service providers.
  • OffsetHigh
    Reserved for use by service providers.
  • hEvent
    If an overlapped I/O operation is issued without an I/O completion routine (lpCompletionRoutine is null), then this parameter should either contain a valid handle to a WSAEVENT object or be null. If lpCompletionRoutine is non-null then applications are free to use this parameter as necessary.

Requirements
