FFLUSH(3)           Linux Programmer's Manual           FFLUSH(3)
+

+
+
NAME
+
       fflush, fpurge - flush a stream
+
+
SYNOPSIS
+
       #include <stdio.h>
+
+       int fflush( FILE *stream);
+       int fpurge( FILE *stream);
+
+
DESCRIPTION
+
       The  function  fflush  forces a write of all buffered data
+       for the given output or update  stream  via  the  stream's
+       underlying  write function.  The open status of the stream
+       is unaffected.
+
+       If the stream argument is NULL, fflush  flushes  all  open
+       output streams. (Does this happen under Linux)
+
+       The function fpurge erases any input or output buffered in
+       the given stream.  For output 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.
+
+
RETURN VALUES
+
       Upon successful completion 0 is returned.  Otherwise,  EOF
+       is  returned and the global variable errno is set to indi-
+       cate the error.
+
+
ERRORS
+
       EBADF  Stream is not an open stream, or, in  the  case  of
+              fflush, not a stream open for writing.
+
+       The function fflush may also fail and set errno for any of
+       the errors specified for the routine write(2).
+
+
BUGS
+
       Linux may not support fpurge.
