[sr-dev] shm_free - not setting pointer to zero?

Richard Good writes:

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.

if shm_free would set the pointer to zero, then you would need to pass pointer's address as argument.

it is not really a problem. you just set the pointer to zero after calling shm_free, for example:

if (rule_pt) { shm_free(rule_pt); rule_pt = 0; }
