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> + +
