setlinebuf()

alter buffering behavior of stream 

Function

SYNOPSIS

#include <stdio.h>

int setlinebuf(FILE *stream);

DESCRIPTION

The setlinebuf() function lets the program control the buffer of a given stream. This function may be used after the stream pointed to by stream is associated with an open file, but before any other operation is performed on the stream. Except that it returns no value, the setlinebuf() function is equivalent to the setvbuf() function invoked with the values (char *)NULL for buffer, _IONBF for mode and zero for size.

PARAMETERS

RETURN VALUES

If successful, setlinebuf() returns 0. On failure, it returns non-zero if an invalid value is given for mode or if the request cannot be honored.
