virtual bool RtcFile::isBytewise ( ) const

inlineprivatevirtual

File subclasses can define this and return true if they require read() calls to perform actual data reads, and false if readBlock() is otherwise sufficient.

Reimplemented from File.

Definition at line 187 of file DevFs.h.

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

virtual

Reads bytes from the file, if isBytewise() == true.

Reimplemented from File.

Definition at line 189 of file DevFs.cc.

bool RtcFile::supports ( const size_t command ) const

virtual

Does this File object support the given integer-based command?

Reimplemented from File.

Definition at line 201 of file DevFs.cc.

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