FFLUSH(3)		 BSD Library Functions Manual		     FFLUSH(3)

NAME
     fflush, fpurge — flush a stream

LIBRARY
     Standard C Library (libc, -lc)

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.

     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(3).

RETURN VALUES
     Upon successful completion 0 is returned.	Otherwise, EOF is returned and
     the global variable errno is set to indicate the error.

ERRORS
     [EBADF]		The stream argument 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).

SEE ALSO
     write(2), fclose(3), fopen(3), setbuf(3)

STANDARDS
     The fflush() function conforms to ISO/IEC 9899:1990 (“ISO C90”).
