Method
GioFileappend_to
Declaration
GFileOutputStream*
g_file_append_to (
GFile* file,
GFileCreateFlags flags,
GCancellable* cancellable,
GError** error
)
Description
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 G_FILE_CREATE_PRIVATE
in flags
the file
will be made readable only to the current user, to the level that
is supported on the target filesystem.
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.
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.
