Hi
Is there any reason why shm_free does not set the pointer it is freeing to zero once it is free-ed?
Code like: *if (pointer) { shm_free(pointer);*
Is not really useful seen as how shm_free does not set the pointer to zero - any double free will still cause a crash.
I suppose it forces the developer to be careful with memory management - is this the only reason?
Regards Richard.
