MemPtrNew() will only allocate the memory for you. It won't call constructors for you like operator new will. If the objects you are creating are of a class which inherits from one or more other classes, keep in mind that C++'s new and constructor mechanisms will also ensure that parent class constructors are also called where appropriate, and will call constructors for each element in object arrays for you. These things are possible to do yourself, but error-prone to keep in synch as an object hierarchy evolves. Another nit which may or may not apply to your chosen C++ environment is that operator new is supposed to throw an exception by default on out-of-memory error, whereas MemPtrNew() returns 0. If you like the new Standard C++ behavior and your C++ environment supports it, you will of course want to use operator new for all memory allocations. In general, use MemPtrNew() in C++ Palm OS programs only where you would use malloc() on other platforms. -- = The Palm OS Programmer's FAQ: http://tangentsoft.net/palmfaq/ = = ICBM Address: 36.8274040 N, 108.0204086 W, alt. 1714m -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
