Detailed Description

FAT Symlink.

FAT itself does not support symlinks, so a Pedigree-specific extension has been used. A filename with a suffix of '.__sym' will be turned into a symlink and its contents will be considered the target of the link.

Definition at line 37 of file FatSymlink.h.

Member Function Documentation

uint64_t FatSymlink::readBytewise	(	uint64_t	location,
		uint64_t	size,
		uintptr_t	buffer,
		bool	bCanBlock = `true`
	)

virtual

Reads from the file.

Parameters

[in]	buffer	Buffer to write the read data into. Can be null, in which case the data can be found by calling getPhysicalPage.
[in]	bCanBlock	Whether or not the File can block when reading

Reimplemented from File.

Definition at line 39 of file FatSymlink.cc.

uint64_t FatSymlink::writeBytewise	(	uint64_t	location,
		uint64_t	size,
		uintptr_t	buffer,
		bool	bCanBlock = `true`
	)

virtual

Writes to the file.

Parameters

[in] bCanBlock Whether or not the File can block when reading

Reimplemented from File.
