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.
