Method
GioInputStreamclose
Declaration [src]
gboolean
g_input_stream_close (
GInputStream* stream,
GCancellable* cancellable,
GError** error
)
Description [src]
Closes the stream, releasing resources related to it.
Once the stream is closed, all other operations will return G_IO_ERROR_CLOSED
.
Closing a stream multiple times will not return an error.
Streams will be automatically closed when the last reference is dropped, but you might want to call this function to make sure resources are released as early as possible.
Some streams might keep the backing store of the stream (e.g. a file descriptor) open after the stream is closed. See the documentation for the individual stream for details.
On failure the first error that happened will be reported, but the close
operation will finish as much as possible. A stream that failed to
close will still return G_IO_ERROR_CLOSED
for all operations. Still, it
is important to check and report the error to the user.
If cancellable
is not NULL
, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED
will be returned.
Cancelling a close will still leave the stream closed, but some streams
can use a faster close that doesn’t block to e.g. check errors.

GError **
The return location for a recoverable error.
The argument can be NULL
.If the return location is not NULL
, then you must initialize it to aNULL
GError*
.The argument will be left initialized to NULL
by the method if there are no errors.In case of error, the argument will be set to a newly allocated GError
; the caller will take ownership of the data, and be responsible for freeing it.
