#include <stdio.h> int main () { char buffer[256]; FILE *f1, *f2; f1=fopen ("f1.txt","w"); f2=fopen ("f2.txt","a"); setbuf ( f1 , buffer ); fputs ("This is sent to the buffered stream: file1",f1); fflush (f1); setbuf ( f2 , NULL ); fputs ("This is sent to the unbuffered stream: file2",f2); fclose (f1); fclose (f2); return 0; }
