Member Function Documentation

virtual const io::path& irr::io::IReadFile::getFileName

(

)

const [pure virtual]

Get name of file.

Returns:

File name as zero terminated character string.

virtual long irr::io::IReadFile::getPos

(

)

const [pure virtual]

Get the current position in the file.

Returns:

Current position in the file in bytes.

virtual long irr::io::IReadFile::getSize

(

)

const [pure virtual]

Get size of file.

Returns:

Size of the file in bytes.

virtual s32 irr::io::IReadFile::read	(	void *	buffer,
		u32	sizeToRead
	)		[pure virtual]

Reads an amount of bytes from the file.

Parameters:

buffer	Pointer to buffer where read bytes are written to.
sizeToRead	Amount of bytes to read from the file.

Returns:

How many bytes were read.

virtual bool irr::io::IReadFile::seek	(	long	finalPos,
		bool	relativeMovement = false
	)		[pure virtual]
