fflush

Defined in header <stdio.h> 
int fflush( FILE *stream );
-

For output streams (and for update streams on which the last operation was output), writes any unwritten data from the stream's buffer to the associated output device.

-

For input streams (and for update streams on which the last operation was input), the behavior is undefined.

-

If stream is a null pointer, all open output streams are flushed, including the ones manipulated within library packages or otherwise not directly accessible to the program.

-

Parameters

- -
stream - the file stream to write out

Return value

Returns zero on success. Otherwise EOF is returned and the error indicator of the file stream is set.

-

Notes

POSIX extends the specification of fflush by defining its effects on an input stream, as long as that stream represents a file or another seekable device: in that case the POSIX file pointer is repositioned to match the C stream pointer (which effectively undoes any read buffering) and the effects of any ungetc or ungetwc that weren't yet read back from the stream are discarded.

-

Microsoft also extends the specification of fflush by defining its effects on an input stream: in Visual Studio 2013 and prior, it discarded the input buffer, in Visual Studio 2015 and newer, it has no effect, buffers are retained.
