size_t Filesystem::IOVecOutput::pwrite	(	const void *	buf,
		size_t	size,
		int64_t	offset
	)

overridevirtual

Write size bytes from buf[] to file starting at the offset position, returning the number of bytes successfully written. This function does not alter the current file position. This function is thread-safe against all other concurrent calls to pread() and pwrite(), but not against any other function of IOProxy.

Reimplemented from Filesystem::IOProxy.
