a question: about SIGCHLD, thanks

[dreamer_shax]

#include<stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>/*fork()函数所在的头文件*/
#include <errno.h>
#include <dirent.h>
#include <setjmp.h>
#include<sys/resource.h>
#include<signal.h>

int i;

static void pri(int signo)
{
	pid_t pid;
	int status;
	
	while( (pid = wait(&status))>0 )
		printf("recevied sigchld,i = %d,pid = %d,status=%d\n",i,pid,status);
}

int main(int argc,char *argv[]) 
{
	char c = 0;
	pid_t pid;
	

	signal(SIGCHLD,pri);

	for(i=0;i<10;i++)
	{
		pid = fork();

		if(pid==0)//child
		{
			
			exit(0);
		}
		else
		{
			printf("parent running,i=%d\n",i);
			
		}
	}
	


}

结果不可预见 ,一个例子 : 为什么后面几个信号会丢失

parent running,i=0
parent running,i=1
recevied sigchld,i = 2,pid = 13772,status=0
recevied sigchld,i = 2,pid = 13773,status=0
parent running,i=2
parent running,i=3
parent running,i=4
parent running,i=5
recevied sigchld,i = 6,pid = 13775,status=0
recevied sigchld,i = 6,pid = 13776,status=0
recevied sigchld,i = 6,pid = 13777,status=0
recevied sigchld,i = 6,pid = 13778,status=0
parent running,i=6
parent running,i=7
parent running,i=8
parent running,i=9

父进程结束的太快了吧
加一条sleep(1)看看
