尝试写一个简单的守护进程

/** @File daemon.c  *    	   *	Build a daemon process for game * */#include 
     
      #include 
      
       #include 
       
        #include "daemon.h"int create_daemon(){	pid_t pid;		pid=fork();	switch(pid)	{		case -1:			//fprintf(stderr, "fork child failed!\n");	 			exit(EXIT_FAILURE);		break;		case 0:			//fprintf(stdout,"child is here!\n");			for(;;)			{				sleep(3);			}		break;		default:			//fprintf(stdout,"child pid is  [%d]\n", pid);		break;		}		return 0;}
       
      
     

　　创建线程

#include 
     
      #include 
      
       #include 
       
        pthread_t create_thread( void* pFunc){		pthread_t tid;	if(pthread_create(&tid, NULL, (void*)pFunc, NULL) == 0)	{		fprintf(stdout, "create thread success!\n");	}else	{		fprintf(stderr, "create thread failed!\n");		exit(EXIT_FAILURE);	}		return tid;}
