12 FILE *stream;

14 fflush(stream)
15 FILE *stream;

18 Fclose causes any buffers for the named stream to be emptied, and the
19 file to be closed. Buffers allocated by the standard input/output sys‐
20 tem are freed.
21
22 Fclose is performed automatically upon calling exit(2).
23
24 Fflush causes any buffered data for the named output stream to be writ‐
25 ten to that file. The stream remains open.
26
28 close(2), fopen(3), setbuf(3)
29
31 These routines return EOF if stream is not associated with an output
32 file, or if buffered data cannot be transferred to that file.
