Member Function Documentation

virtual XioStatus XrdSfsXio::Swap	(	const char *	curBuff,
		XrdSfsXioHandle *&	curHand,
		XrdSfsXioHandle *	oldHand = 0
	)			[pure virtual]

Swap the current I/O buffer

Parameters:

	curBuff	- The address of the current buffer. It must match the the buffer that was most recently passed to the caller.
	curHand	- Where the handle associated with curBuff is to be placed.
	oldHand	- The handle associated with a buffer returned by a previous call to Swap(). A value of zero indicates that the caller is taking control of the buffer but has no replacement buffer.

Returns:

!allOK One or more arguments or context is invalid. Nothing was swapped. The returned value describes the problem. The curHand has been set to zero.

=allOK The handle associated with curBuff has been placed in curHand. This handle must be used in a future Swap() call.
