Re: problem passing pointer array

You also don't check the return value of malloc. It could be NULL, in

Also the design is flawed, mainly because this works only for arrays
of ints, and because 40 is hardcoded, how about you change this to
struct vector { size_t nmemb, size; void *elements; };
struct vector *remove_if(const struct vector *v, int (*remove)(void
*));

though I don't like the 'remove_if' name, I chose it because there's a
similar function in common lisp named REMOVE-IF.

Well, I wrote the function just as a test function to understand about
array of pointers. Just chose int to make things simple.
