CArchive::Read

Reads a specified number of bytes from the archive.

UINT Read(
   void* lpBuf,
   UINT nMax 
);

Parameters

  • lpBuf
    A pointer to a user-supplied buffer that is to receive the data read from the archive.

  • nMax
    An unsigned integer specifying the number of bytes to be read from the archive.

Return Value

An unsigned integer containing the number of bytes actually read. If the return value is less than the number requested, the end of file has been reached. No exception is thrown on the end-of-file condition.

Remarks

The archive does not interpret the bytes.

You can use the Read member function within your Serialize function for reading ordinary structures that are contained in your objects.

Example

char pbRead[100];
ar.Read(pbRead, 100);
