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有効になっています。チェックを無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 ルールを追加してください。 
WARNING_FILTER += discard class="Inappropriate Call Outside Loop"

例 

#include <pthread.h>

unsigned int test;

void wait_inside_loop(pthread_cond_t cond, pthread_mutex_t lock){
    pthread_mutex_lock(&lock);
    while (test == 0)
        pthread_cond_wait(&cond, &lock);                       /* ok: call is inside a loop */
    test = 0;
    pthread_mutex_unlock(&lock);
}

void wait_outside_loop(pthread_cond_t cond, pthread_mutex_t lock){
    pthread_mutex_lock(&lock);
    pthread_cond_wait(&cond, &lock);  /* 'Inappropriate Call Outside Loop' warning issued here */
    test=1;
    pthread_mutex_unlock(&lock);
}
