|
|
.Sh SYNOPSIS
|
|
.In stdio.h
|
|
.Ft int
|
|
.Fn fclose "FILE *stream"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Fn 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
|
|
.Xr fflush 3 .
|
|
.Sh RETURN VALUES
|
|
Upon successful completion 0 is returned.
|
|
Otherwise,
|
|
.Dv EOF
|
|
is returned and the global variable
|
|
.Va errno
|
|
is set to indicate the error.
|
|
In either case no further access to the stream is possible.
|
|
.Sh ERRORS
|
|
The
|
|
.Fn fclose
|
|
function
|
|
may also fail and set
|
|
.Va errno
|
|
for any of the errors specified for the routines
|
|
.Xr close 2
|
|
or
|
|
.Xr fflush 3 .
|
|
.Sh NOTES
|
|
The
|
|
.Fn 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.

.Sh STANDARDS
|
|
The
|
|
.Fn fclose
|
|
function
|
|
conforms to
|
|
.St -isoC .
