The
fclose();
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).
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
[EBADF]
The argument
stream
is not an open stream.
The
fclose();
function may also fail and set
errno
for any of the errors specified for the routines
close(2)
or
fflush(3).
