Hi, does anybody ever work with realloc() and RTX-51 together? do malloc(), free(), realloc() functions make some trouble when work with multitasks? Since RTX-51 only can manage the fix size memory pools, according to my application, every message I got is available in size. So it is some inconvienent to use RTX-51 memory manage function, thought it can give me easy way to help out. But the Ram of the hardware is so limited on my project, I'd manage to take every bytes in use. Can anybody give me some advice.
