LANG.TYPE.IVD : Inappropriate Volatile Declaration

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

有効/無効設定

このワーニングクラスのチェックはデフォルトで無効になっており、プロジェクトには非正規の C向けAST が必要になります。有効にするにはプロジェクト設定ファイル（configuration file）に以下の WARNING_FILTER ルールと RETAIN_UNNORMALIZED_C_AST 設定を追加してください。

RETAIN_UNNORMALIZED_C_AST = Yes
WARNING_FILTER += allow class="Inappropriate Volatile Declaration"

注：非正規化された AST を継続して使用した場合、使用ディスク容量が増加し解析時間が長くなる可能性があります。

例

typedef int volatile vint;

void lang_type_ivd(volatile int i, /* 'Inappropriate Volatile Declaration' warning issued here */
                   vint vi) {      /* 'Inappropriate Volatile Declaration' warning issued here */
    volatile int x;                /* 'Inappropriate Volatile Declaration' warning issued here */
    int * volatile vpi;            /* 'Inappropriate Volatile Declaration' warning issued here */
    volatile int *pvi;                     /* ok: pvi is a nonvolatile pointer to volatile int */
