Public Member Functions inherited from joedb::Abstract_File
virtual int64_t	get_size () const
	Get the size of the file, or -1 if it is unknown.

virtual size_t	pread (char *data, size_t size, int64_t offset) const
	Read a range of bytes.

virtual void	pwrite (const char *data, size_t size, int64_t offset)
	Write a range of bytes. Extend file size if necessary.

virtual void	sync ()
	Write data and meta-data (such as file size) durably to permanent storage.

virtual void	datasync ()
	Write data durably to permanent storage.

virtual void	shared_lock (int64_t start, int64_t size)
	Lock a range of bytes for reading (prevents writes, not reads)

virtual void	exclusive_lock (int64_t start, int64_t size)
	Lock a range of bytes for writing (prevents both writes and reads)

virtual void	unlock (int64_t start, int64_t size) noexcept
	Remove a lock. The range should match the range of a corresponding lock.
