FPURGE(3)                  Linux Programmer's Manual                 FPURGE(3)



NAME
       fpurge, __fpurge - purge a stream

SYNOPSIS
       /* unsupported */
       #include <stdio.h>

       int fpurge(FILE *stream);

       /* supported */
       #include <stdio.h>
       #include <stdio_ext.h>

       void  __fpurge(FILE *stream);

DESCRIPTION
       The function fpurge() clears the buffers of the given stream.  For out‐
       put streams this discards any unwritten output.  For input streams this
       discards any input read from the underlying object but not yet obtained
       via getc(3); this includes any text pushed  back  via  ungetc(3).   See
       also fflush(3).

       The  function __fpurge() does precisely the same, but without returning
       a value.

RETURN VALUE
       Upon successful completion fpurge() returns 0.  On error, it returns -1
       and sets errno appropriately.

ERRORS
       EBADF  stream is not an open stream.

CONFORMING TO
       These  functions  are  nonstandard  and  not  portable.   The  function
       fpurge() was introduced in 4.4BSD and is  not  available  under  Linux.
       The  function  __fpurge()  was introduced in Solaris, and is present in
       glibc 2.1.95 and later.

NOTES
       Usually it is a mistake to want to discard input buffers.
