+.TH FCLOSE 3  1993-11-29 "BSD MANPAGE" "Linux Programmer's Manual"
+.SH NAME
+fclose \- close a stream
+.SH SYNOPSIS
+.B #include <stdio.h>
+.sp
+.BI "int fclose(FILE *" fp );
+.SH DESCRIPTION
+The
+.B fclose
+function will flush the stream pointed to by
+.IR fp
+(writing any buffered output data using
+.BR fflush (3))
+and close the underlying file descriptor.
+.SH "RETURN VALUE"
+Upon successful completion 0 is returned.  Otherwise,
+.B EOF
+is returned and the global variable
+.I errno
+is set to indicate the error.  In either case any further access
+(including another call to
+.BR fclose ())
+to the stream results in undefined behaviour.
+.SH ERRORS
+.TP
+.B EBADF
+The filedescriptor underlying
+.I fp
+is not valid.
+.\"  This error cannot occur unless you are mixing ANSI C stdio operations and
+.\"  low-level file operations on the same stream. If you do get this error,
+.\"  you must have closed the stream's low-level file descriptor using
+.\"  something like close(fileno(fp)).
+.PP
+The
+.B fclose
+function may also fail and set
+.I errno
+for any of the errors specified for the routines
+.BR close (2),
+.BR write (2)
+or
+.BR fflush (3).
+.SH NOTES
+Note that
+.B fclose
+only flushes the user space buffers provided by the
+C library. To ensure that the data is physically stored
+on disk the kernel buffers must be flushed too, e.g. with
+.BR sync (2)
+or
+.BR fsync (2).
+.SH "CONFORMING TO"
+The
+.B fclose
+function conforms to ANSI X3.159-1989 (``ANSI C'').
+.SH "SEE ALSO"

+.BR fcloseall (3),
