This method reads data retrieved by the pluggable protocol handler.

Syntax

HRESULT Read(
  void* pv,
  ULONG cb,
  ULONG* pcbRead
);

Parameters

  • pv
    [in, out] Address of the buffer where the information will be stored.
  • cb
    [in] ULONG value that indicates the size of the buffer.
  • pcbRead
    [out] Address of a ULONG value that indicates the amount of data stored in the buffer.

S_OK

The read was successful, but there is still additional data available.

S_FALSE
