我需要杀死这种使用过程,这些使用过程需要的时间比UNIX(Solaris)操作系统的预期间隔时间长。 需要在目前正在执行的进程中这样做。
请建议如何在C或UNIX做到这一点?
见alarm( system calls。 它向您提供贵国可以处理并用于填写的<代码>SIGALRM信号。
只要在无警告的情况下杀人,加班过程是可以接受的,一种替代办法是,在启动程序时使用<条码>限制――t <time>。
有了<代码>setrlimit,你可以限制该过程所用的CPU时间。 一旦超过限额,你将获得<代码>SIGXCPU。
#include <sys/resource.h>
struct rlimit limits = {42, RLIM_INFINITY};
setrlimit(RLIMIT_CPU, &limits);
我必须同时解决这一完全相同的问题。
我的解决办法如下:
起草控制员方案,其内容如下:
办法比较容易。 然后,在主线上打电话。 这将等待这么长时间。 如果该声明的回归和工人的read子仍在运行,那么你就可以杀死和撤出。
