还是先看一下代码吧!!
- int my_exec(char **cmd,int flag)
- {
- int status = 0;
- int pid = 0;
- if((pid=fork())==0){
- execv(cmd[0],cmd);
- fprintf(stderr,"execv():%s .\n",strerror(errno));
- exit(errno);
- //child !
- }
- else if(pid == -1 ){ ///error .
- fprintf(stderr,"fork():%s \n",strerror(errno));
- return pid;
- }
- if(flag == 0){//father
- waitpid(pid,&status, WNOHANG);
- return WEXITSTATUS(status);
- }
- else if (flag == 1 )
- return pid;
- return (!0);
- }
复制代码
- void handler()
- {
- FILE *fd = NULL;
- char *fpath ="/proc/net/dev";
- ppp *p = NULL;
- char *stt = NULL;
- char *cmd[]={"/home/codes/script/pppoecount.sh",username,"8",NULL};
- alarm(2);
- fd= fopen (fpath, "r" );
- if(!fd){
- g_print("Can't fopen(): %s :%s\n",fpath,strerror(errno));
- return;
- }
- //g_print("come to handler for alarm .\n");
- p = get_ppps(fd);
- stt = sprint_ppp(p);
- if(g_strrstr(stt,"eth"))t_sec+=2;
- else t_sec = 0;
- sprintf(&stt[strlen(stt)],"ppp time: %ld:%ld:%ld.\n",t_sec/(3600),(t_sec/60)%60,t_sec%60);
- if(label)gtk_label_set_text(GTK_LABEL(label),stt);
- free_ppp(p);
- ////////////////////// 只能这样做标记了
- if(t_sec%8==0my_exec(cmd,1);
- /////////////////////
- if(fd)fclose(fd);
- }
复制代码

脚本都运行结束了啊!!
[pppoecount.sh] <defunct> 为什么还在啊??
当然如果程序关闭,[pppoecount.sh] <defunct> 就没有了!
这个东西有点烦人,恳请有人能帮我把它弄掉??
