wrpipe.c

中科院徐志伟老师一书《操作系统 原理·技术与编程》的源代码和习题接

#include <unistd.h>
#include <stdio.h>
#include <string.h>
char *id = "wr_pipe.c is a test named_pipe example\n";
void main(){
FILE *filp;
int count = 1;
char buf[128];
write(2,id,strlen(id));

filp = fopen("named_pipe","w");
   if(filp ==NULL){
      perror("fopen");
      exit(1);
   }
sprintf(buf,"It is really interesting,I like this experience.\n");
fwrite(buf,1,strlen(buf),filp);
fclose(filp);
}
