function file_set_contents(filename: String, contents: ByteArray): Boolean {
    // Gjs wrapper for g_file_set_contents()

Writes all of contents to a file named filename, with good error checking. If a file called filename already exists it will be overwritten.

This write is atomic in the sense that it is first written to a temporary file which is then renamed to the final name. Notes:

- On UNIX, if filename already exists hard links to filename will break. Also since the file is recreated, existing permissions, access control lists, metadata etc. may be lost. If filename is a symbolic link, the link itself will be replaced, not the linked file.

- On Windows renaming a file will not remove an existing file with the new name, so on Windows there is a race condition between the existing file being removed and the temporary file being renamed.

- On Windows there is no way to remove a file that is open to some process, or mapped into memory. Thus, this function will fail if filename already exists and is open.

If the call was successful, it returns true. If the call was not successful, it returns false and sets @error. The error domain is #G_FILE_ERROR. Possible error codes are those in the GLib.FileError enumeration.

Note that the name for the temporary file is constructed by appending up to 7 characters to filename.
