warn_no_side_effect
Controls the issuing of warnings for redundant statements.
Prototype
#pragma warn_no_side_effect on | off | reset
Remarks
If you enable this pragma, the compiler issues a warning when it encounters a
statement that produces no side effect. To suppress this warning, cast the statement
with (void). Listing C.28
provides an example.
Listing C.28 Example of Pragma warn_no_side_effect
#pragma warn_no_side_effect on
void foo(int a,int b)
{
a+b; // WARNING: expression has no side effect
(void)(a+b); // void cast suppresses warning
}
This pragma does not correspond to any panel setting in the C/C++ Preprocessor
panel. To check this setting, use __option (warn_no_side_effect),
described in Checking Settings
. By default, this pragma is disabled.
warn_notinlined
Controls the issuing of warnings for functions the compiler cannot inline.
Prototype
#pragma warn_notinlined on | off | reset
Remarks
The compiler issues a warning for non-inlined inline function calls.
