類中的p線程函數。假設我有一個類似的類class c {
// ...
void *print(void *){ cout << "Hello"; }}然后我有一個c的向量vector<c> classes; pthread_t t1;classes.push_back(c());classes.push_back(c());現在，我想在c.print();以下是我的問題：pthread_create(&t1, NULL, &c[0].print, NULL);錯誤輸出：無法轉換‘void*(tree_tem：)(無效)“to”無效*()(無效)‘for參數’3‘to’int pline_create(p線程_t*，const p線程_attr_t*，void*()(無效)，無效*‘
