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. <h3>RETURN VALUES </h3> Upon successful completion 0 is returned. Otherwise, EOF is returned and the global variable errno is set to indi- cate the error. <h3>ERRORS </h3> 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). <h3>BUGS </h3> Linux may not support fpurge. </pre> <hr> <h3>SEE ALSO </h3><p> <a href=write.htm>write</a>, <a href=fopen.htm>fopen</a>, <a href=fclose.htm>fclose</a>, <a href=setbuf.htm>setbuf</a>, <pre> <h3>STANDARDS </h3> The fflush function conforms to ANSI C3.159-1989 (``ANSI C''). <h3>BSD MANPAGE 29 November 1993 1 </h3> </pre> <P> <hr> <p> <center> <table border=2 width=80%> <tr align=center> <td width=25%> <a href=../index.htm>Top</a> </td><td width=25%> <a href=../master_index.html>Master Index</a> </td><td width=25%> <a href=../SYNTAX/keywords.html>Keywords</a> </td><td width=25%> <a href=../FUNCTIONS/index.htm>Functions</a> </td> </tr> </table> </center> <p> <hr> This manual page was brought to you by <i>mjl_man V-2.0</i>
