Read Method of the IReadStream Interface

This method is implemented on the client side. This method reads the specified number of bytes from the stream.

Syntax

Visual Basic .NET

Function Read( _
  ByRef Data() As Byte, _
  ByVal Count As Integer _
) As Integer
    

C++

HRESULT Read(
  SAFEARRAY(BYTE)* Data,
  int              Count,
  int*             BytesRead
);
    

Parameters

Data
[out] This parameter refers to the data to be read.
Count
[in] This parameter specifies the number of bytes to be read.
BytesRead
[out, retval] This parameter specifies the number of bytes transmitted.

Return values

[C++ only] If this method returns a value other than S_OK, this indicates that an error occurred on the client side.

Remarks

A client implementation of this method must assure that all exceptions thrown inside the method are caught and handled and no exceptions are propagated outside the method. Propagation of an exception outside the method may lead to unpredictable results (such as program termination).
