8/// Updates the DHCP client preferences to include the
9/// given list of options for the given application ID.
10///
11/// Parameter `applicationID`: The application's preference ID, for example:
12/// "com.apple.SystemPreferences".
13///
14/// Parameter `options`: An array of 8-bit values containing the
15/// DHCP option codes (see RFC 2132) for this application ID.
16/// A NULL value will clear the list of options for this
17/// application ID.
18///
19/// Parameter `count`: The number of elements in the options parameter.
20///
21/// Returns: Returns TRUE if the operation succeeded, FALSE otherwise.
22///
23/// # Safety
24///
25/// `options` must be a valid pointer or null.
