NAME
fclose, fcloseall
— close a stream
LIBRARY
library “libc”
SYNOPSIS
#include
<stdio.h>
int
fclose(FILE
*stream);
void
fcloseall(void);
DESCRIPTION
Thefclose()
function dissociates the named stream from its
underlying file or set of functions. If the stream was being used for output,
any buffered data is written first, using
fflush(3).
The
fcloseall()
function calls fclose() on all open streams.
RETURN VALUES
Upon successful completion 0 is returned. Otherwise,
EOF is returned and the global variable
errno is set to indicate the error. In either case no
further access to the stream is possible.
ERRORS
The fclose() function may also fail and
set errno for any of the errors specified for the
routines close(2) or
fflush(3).
NOTES
The fclose() function does not handle NULL
arguments; they will result in a segmentation violation. This is intentional
- it makes it easier to make sure programs written under
DragonFly are bug free. This behaviour is an
implementation detail, and programs should not rely upon it.
SEE ALSO
STANDARDS
The fclose() function conforms to
ISO/IEC 9899:1990
(“ISO C90”).
The fcloseall() function first appeared in
DragonFly 2.3.
