In my company there is a coding rule that says, after freeing any memory, reset the variable to NULL. For example …
void some_func ()
{
int *nPtr;
nPtr = malloc (100);
free (nPtr);
nPtr = NULL;
return;
}
I feel that, in cases like the code shown above, setting to NULL does not have any meaning. Or am I missing something?
If there is no meaning in such cases, I am going to take it up with the “quality team” to remove this coding rule. Please advice.
