2、捕捉到信號(hào)后分別輸出下列信息后終止：Child Processll is Killed by Pare nt!Child Processl2 is Killed by Pare nt!父進(jìn)程等待兩個(gè)子進(jìn)程終止后，輸出如下的信息后終止Pare nt Process is Killed!四、設(shè)計(jì)思路和流程圖五、源程序:#i nclude #in cludevsig nal.h #in cludev un istd.h #i ncludestdlib.hint wait mark;void wait in g()sleep(5);if(wait_mark != 0) kill(getpid(), S
