setbuf¶

Synopsis¶

#include <stdio.h>

void setbuf(FILE *restrict stream, char *restrict buf);

Partially implemented

IEEE Std 1003.1-2017

The purpose is to assign buffering to a stream.

Except that it returns no value, the function call:

setbuf(stream, buf)

shall be equivalent to:

setvbuf(stream, buf, _IOFBF, BUFSIZ)

If buf is not a null pointer, or to:

setvbuf(stream, buf, _IONBF, BUFSIZ)s

If buf is a null pointer.

The setbuf() function shall not return a value.

Although the setvbuf() interface may set errno in defined ways, the value of errno after a call to setbuf() is unspecified.

Untested
