setbuf()

This is a file I/O function, also hardware dependent. It is not implemented in this Compiler.

#include <stdio.h>

  

  void setbuf(FILE *f, char *buf);

  

setbuf() lets you specify how a file is buffered. If buf is NULL, the file is unbuffered (all input or output goes directly to and comes directly from the file). If buf is not NULL, it is used as a buffer ( buf points to an array of BUFSIZ bytes).
