|
13 <p> Controls the recognition of unreferenced arguments.</p> |
|
14 <h5>Syntax</h5> |
|
15 <p class="code">#pragma warn_unusedarg on | off | reset</p> |
|
16 <h5>Targets</h5> |
|
17 All platforms.<br /> |
|
18 <h5>Remarks</h5> |
|
19 <p>If you enable this pragma, the compiler issues a warning when it encounters an argument you declare but do not use. For more information about this warning, see “Unused Arguments”. To suppress this warning in C++ source code, leave an argument identifier out of the function parameter list. Listing 10.33 shows an example.</p> |
|
20 <p> This pragma corresponds to the Unused Arguments setting . To check this setting, use <span class="code">__option (warn_unusedarg)</span>, described in <a href="../symbols/sym_settings.htm">Checking Settings</a>. The default setting is <span class="code">off</span>. </p> |
