a string containing the new contents for file
the old entity-tag for the document, or null
true if a backup should be created
a set of #GFileCreateFlags
a location to a new entity tag for the document. This should be freed with glib.global.gfree when no longer needed, or null
optional #GCancellable object, null to ignore
true if successful. If an error has occurred, this function will return false and set error appropriately if present.
Replaces the contents of file with contents of length bytes.
If etag is specified (not null), any existing file must have that etag, or the error gio.types.IOErrorEnum.WrongEtag will be returned.
If make_backup is true, this function will attempt to make a backup of file. Internally, it uses gio.file.File.replace, so will try to replace the file contents in the safest way possible. For example, atomic renames are used when replacing local files’ contents.
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 gio.types.IOErrorEnum.Cancelled will be returned.
The returned new_etag can be used to verify that the file hasn't changed the next time it is saved over.
