Hey Mayank, > I'm supposed to port a C++ application from Windows to Palm.
Ah well! One more windows app gets on palm. cool. :-) > This application heavily uses standard C++ library functions Hmmm. So please be advised that other than new and delete, you would have to take care of the functions that your windows application uses and you wont find them in palm. For e.g. palm environment does not have the standard C library ( or at least not exposed to application developers ) so one should really be making use of the calls of the undelrying OS i.e. Palm for various functionalities. Thus, you would have to replace all the occurences of strcpy() with StrCopy() of String Manager ( or perhaps with some API from Text Manager if you plan to internationalise your app in the future )! > - new and delete > for memory allocation/deallocation . As per the C++ Standards, the new keyword is supposed to do _two_ things : 1. Allocate the memory for an object from the heap 2. Having allocated the memory, run the objects constructor on that allocated memory. If you plan to use MemPtrNew() and MemPtrFree() as the parallel calls for new and delete in your app, please rememebr that MemPtrNew() would allocate the memory for you, but it will _not_ call the constructor on that memory. AFAIK, the implementation of new keyowrd on Palm is such that it always calls the MemPtrNew() API of the Memory Manager internally...so you are really given a direct physical address by the system. Since this poiner is not locked, it may become a dangling pointer should the system run a "compaction" routine or other similar job behind your back. So, the wise thing to do would be to use the new only if you are sure you are not gonna need the object for longer periods of times. Guys, please correct me if I am wrong.
