1.c

用简单的例子实现了用命名管道实现进程间通信

#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <dirent.h>

int main()
{
        DIR * dp = NULL;
        struct dirent * entry = NULL;
        char * fifo_name;

        dp = opendir("/tmp");
        while((entry = readdir(dp))!=NULL)
        {
                if(strncmp(entry->d_name,"my_fifo_",8)==0)
                {
                        fifo_name = entry->d_name+8;
                        printf("%s\n",fifo_name);
                }
        }
}
