/**
|
|
sl@0
|
28 |
A convenience postfix macro that is equivalent to wrapping the
|
|
sl@0
|
29 |
preceding expression with User::LeaveIfError().
|
|
sl@0

|

The code:
|
|
sl@0
|
32 |
@code
|
|
sl@0
|
33 |
fs.Connect() OR_LEAVE;
|
|
sl@0
|
34 |
@endcode
|
|
sl@0
|
35 |
|
|
sl@0
|
36 |
is equivalent to:
|
|
sl@0
|
37 |
|
|
sl@0
|
38 |
@code
|
|
sl@0
|
39 |
User::LeaveIfError(fs.Connect());
|
|
sl@0
|
40 |
@endcode
|
|
sl@0
|
41 |
|
|
sl@0
|
42 |
The implementation happens to rely on overloading operator|| for
|
|
sl@0
|
43 |
TLeave. However, this macro is not intended for use within general
|
|
sl@0
|
44 |
expressions, just to guard individual calls to methods that may
|
|
sl@0
|
45 |
return an error code.
