List of all members.

Public Member Functions
int	Open (char *Name, int Attrib)
	Opens a file.
bool	IsOpen ()
	Returns non zero if the class is associated with an open file handle.
int	Close ()
	Closes the file.
int	GetOpenMode ()
	Gets the mode that the file was openned with.
int64	GetPos ()
	Gets the current file pointer.
int64	SetPos (int64 Pos)
	Sets the current file pointer.
int64	GetSize ()
	Gets the file size.
int64	SetSize (int64 Size)
	Sets the file size.
int	Read (void *Buffer, int Size, int Flags=0)
	Reads bytes into memory from the current file pointer.
int	Write (void *Buffer, int Size, int Flags=0)
	Writes bytes from memory to the current file pointer.
char *	GetName ()
	Gets the path used to open the file.
int64	Seek (int64 To, int Whence)
	Moves the current file pointer.
bool	Eof ()
	Returns true if the current file pointer is at the end of the file.
