DmComparF is not a function, but rather is a typedef for a certain type of function. You need to write a function yourself that matches the function signature in that typedef. You'll write this "callback" function but never actually call it. You just pass the callback function's address to the system in the DmQuickSort call, and then the system will call it automatically several times during the sort, as needed. This callback function has to simply compare two records and return a result saying if they are equal, or which one is greater. Since you want alphabetical order, your callback will probably involve StrCompare or similar logic. This whole callback mechanism is used because the system has no idea of the internal format of your database records. So the system asks you to help it out with your own custom function that does know the format and how to compare them. The API documentation covers the details... -slj- -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
