#include <sys/wait.h> exec 功能:在用f o r k函数创建子进程后,子进程往往要调用一个e x e c函数以执行另一个程序 当进程调用一种e x e c函数时,该进程完全由新程序代换,而新程序则从其m a i n函数开始执行。因为调用e x e c并不创建新进程,所以前后的进程I D并未改变。e x e c只是用另一个新程序替

如果发现 w.base == w.top 或者tryRemoveAndExec返回true说明自己所属的队列为空,也说明我们通过fork将本线程的任务已经被别的线程偷走,该线程也不会闲着,将会helpStealer帮助帮助自己执行任务的线程执行任务(互惠互利,你来我往) 如果tryCompensate为true,则阻塞本线程,等待任务执行结束的唤醒 tryRemoveAndExec 如果joi...
