GFileOutputStream* g_file_append_to ( GFile* file, GFileCreateFlags flags, GCancellable* cancellable, GError** error )
Gets an output stream for appending data to the file. If the file doesn’t already exist it is created.
By default files created are generally readable by everyone,
but if you pass
flags the file
will be made readable only to the current user, to the level that
is supported on the target filesystem.
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.
Some file systems don’t allow all file names, and may return an
G_IO_ERROR_INVALID_FILENAME error. If the file is a directory the
G_IO_ERROR_IS_DIRECTORY error will be returned. Other errors are
possible too, and depend on what kind of filesystem the file is on.
|The caller of the method takes ownership of the data, and is responsible for freeing it.|
