Constructor & Destructor Documentation

◆ LinnFile()

LinnFile::LinnFile	(	LinnFileSystem *	fs,
		const u32	inode,
		LinnInode *	inodeData
	)

Constructor function.

Parameters

fs	LinnFS filesystem pointer.
inode	Inode number
inodeData	Inode data pointer.

Definition at line 22 of file LinnFile.cpp.

References File::m_access, m_inodeData, File::m_size, LinnInode::mode, and LinnInode::size.

◆ ~LinnFile()

LinnFile::~LinnFile ( )

virtual

Member Function Documentation

◆ read()

FileSystem::Result LinnFile::read	(	IOBuffer &	buffer,
		Size &	size,
		const Size	offset
	)

virtual

Read bytes from the file.

Parameters

buffer	Input/Output buffer to output bytes to.
size	Maximum number of bytes to read on input. On output, the actual number of bytes read.
