Done()

void XrdOucCallBack::Done ( int &  Result, XrdOucErrInfo *  eInfo, const char *  Path = 0  )

inlineprivatevirtual

Invoke a callback after an operation completes.

Parameters

Result	- the original function's result (may be changed).
eInfo	- Associated error information. The eInfo object may not be modified until it's own callback Done() method is called, if supplied. If the callback function in eInfo is zero, then the eInfo object is deleted by the invoked callback. Otherwise, that method must be invoked by this callback function after the actual callback message is sent. This allows the callback requestor to do post-processing and be asynchronous being assured that the callback completed.
Path	- Optionally, the path related to thid request. It is used for tracing and detailed monitoring purposes.

Implements XrdOucEICB.

Same()

int XrdOucCallBack::Same ( unsigned long long  arg1, unsigned long long  arg2  )

inlineprivatevirtual

Determine if two callback arguments refer to the same client.

Parameters

arg1	- The first callback argument.
arg2	- The second callback argument.

Returns

!0 - The arguments refer to the same client.

=0 - The arguments refer to the different clients.
