Hi, Personally, I felt that "MemPtrFree" is missing something. Although it did release the memory back to the OS, but it seems to be still holding some information of that memory block.
Since there are 2 ways (maybe more) of freeing a memory, there are also 2 ways of creating memory space. We shall use a memory space of 10 bytes as an illustration. For example, Sample "A" : testPtr = MemHandleLock(MemHandleNew(10)); Sample "B" : testPtr = MemPtrNew(10); Both of the sample written above did create a memory space of 10 bytes. However, there is some distinct differences between them. For sample "A", we could use the API "MemPtrRecoverHandle" to recover the handle of that memory block and perform a resizing (bigger or smaller) via the API "MemHandleResize". However, sample "B" is not able to recover any handle from it. Does that mean that it does not contain any handle that contain information about that memory block ? Nevertheless, Palm did have another API for performing resizing for memory block created using "MemPtrNew"by using "MemPtrResize". But, it only works for down sizing and not upsizing (maybe I'm unlucky). If I remember correctly, I think I have read something about Memory Management written in PowerPoint presentation slides by Palm. From the slides, there seems to be some differences between handles and pointer. Although both if them seems to be pointing to the memory block, but it is of different agenda. In conclusion, I felt that "MemPtrNew" seems to contain lesser information that "MemHandleNew" and thus "MemPtrFree" maybe missing something. But that ofcourse, it is my personal observation and maybe wrong. Any comments are most welcome to better understand those API.
