Message: [QUOTE="CBFalconer, post: 1710549"] This will probably never be noticed in the noise generated on the thread. However: char *ptr; int main(void) { if (ptr) .... .... } carries the meaning "does ptr exist". It will have been statically initialized to NULL, or (void *)0 with the intrinsic meaning "no such beastie exists". Similarly for a NULL return from malloc. I.e. my point is that the meaning of NULL is "I don't exist". Whether or not a test for NULLity should involve a specific comparison has no specific answer. At times, the == NULL (or != NULL) will emphasize something or other, and is useful. At other times it is pointless. It is simply not worth something like 60 articles with varying levels of invective. Is this post very useless, or very very useless. Maybe useless. [/QUOTE]
