Detailed Description

Archive raw block stream.

Opens an independent stream over one raw, uncompressed and unencrypted block. Each opened BlockStream owns its own cursor and keeps the source Archive alive until close(). ArchiveMgr::close(idCDC) releases archive ownership, but the Archive stays alive while streams remain open.

Member Function Documentation

◆ close()

Sint32 CRM64Pro::Archive::BlockStream::close ( )

Close the stream.

Returns: 0 on success, or a negative error code on failure.

◆ read()

Sint64 CRM64Pro::Archive::BlockStream::read	(	void *	pDst,
		Uint64	iSize )

Read bytes from the stream.

Parameters

pDst	destination buffer.
iSize	maximum bytes to read.

Returns: number of bytes read, or a negative error code on failure.

◆ seek()

Sint32 CRM64Pro::Archive::BlockStream::seek ( Uint64 iPosition )

Seek the stream.

Parameters

iPosition byte position from the start of the block.

Returns: 0 on success, or a negative error code on failure.

◆ tell()

Uint64 CRM64Pro::Archive::BlockStream::tell ( ) const

Get the current byte position from the start of the block.

Returns: Current byte offset from the beginning of the stream.

◆ size()

Uint64 CRM64Pro::Archive::BlockStream::size ( ) const

Get the stream size in bytes.

Returns: Total stream size in bytes.

◆ eof()

bool CRM64Pro::Archive::BlockStream::eof ( ) const

Check end-of-stream state.

Returns: true if the current byte position is at or past the end of the stream, false otherwise.

◆ isOpen()

bool CRM64Pro::Archive::BlockStream::isOpen ( ) const

Check if the stream is open.

Returns: true if the stream is open, or false otherwise.
