Color Picker-Defined Functions / Responding to Requests to Return and Set Color Picker Information

MyGetPrompt
Color picker-defined subroutine that handles a kGetPrompt request.
If you create a color picker, it must respond to the kGetPrompt request code. The Color Picker Manager sends this code to obtain the prompt string currently used by your color picker. A color picker responds to the kGetPrompt request code by calling a color picker-defined subroutine (for example, MyGetPrompt) to handle the request.
pascal ComponentResult MyGetPrompt (
PickerStorageHndl storage, 
Str255 prompt);
storage
A handle to your color picker's global data.
prompt
Your color picker's prompt string.

DISCUSSION
Your MyGetPrompt function should return the current prompt for your color picker in the prompt parameter.
Your function should return noErr if successful, or an appropriate result code otherwise.
