1.32 +A RZipFileMemberReaderStream represents a input stream for compressed files in the archive.
1.33 +This is a friend class to CZipFile. In order to create a input stream for a file in the archive,
1.34 +CZipFile will call its member function GetInputStreamL() by passing a pointer to
1.35 +RZipFileMemberReaderStream and the function will return the input stream for the file
1.36 +Note: This class is actually a C class as it derives from CBase
