#include <stdio.h> int
fclose (FILE *stream); void
fcloseall (void);
DESCRIPTION
The
fclose ();
function
dissociates the named
Fa 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
Fx are bug free.
This behaviour is an implementation detail, and programs should not
rely upon it.
