我有传承功能,利用小型(小型)来分配记忆。 我在不释放有活力的传承记忆的情况下,用read子杀了read。 一旦一只叫 p-技能,或者会发生泄漏,是否会自动释放吗?
你们的记忆正以一对面的“归属”分配到那个深层。 它是利用你方案,从同一全球范围内分配的。 因此,你必须释放你以其他方式分配的所有记忆,以防泄漏。
正如Civatcu所说,会出现泄漏。
采用<条码>pthread_training/code> 除非你绝对必须这样做。 相反,你应建立一个信号机制,让读者知道何时应该结束,然后加入到底。 可怕的职能应当偶尔污染这一价值,如果它得到终止信号,它就应当清理自己的资源和撤出。
当然,另一个选择是试图避免在read中分配记忆。 但我猜测,你总是不会获得这种奢侈品。
将出现泄漏。 read子的杀功能如何可能知道通过小鼠分配的变量名称? 在C区没有垃圾收集,如果你在某个地方叫小公司,你会更好地确保你在其他地方自由。
[Edit] Maybe you should just set a global flag variable associated with your thread, and have your thread poll that variable occasionally to know if and when it should terminate itself.
<>strong>Yes,假定你没有安装信号手,用于信号的默认行动是程序终止。
这是因为pthread_并不杀死一只read子,而是向read发出信号。 如果该信号的行动是终止process,那么整个过程就不再存在,而且在此过程中,由any分配的任何动态记忆就不复存在。
没有任何东西可以杀.。
