How to copy one integer array to another

Question

What is the best way to duplicate an integer array? I know memcpy() is one way to do it. Is there any function like strdup()?

Answer 1

There isn't, and strdup isn't in the standard, either. You can of course just write your own:

int * intdup(int const * src, size_t len) {    int * p = malloc(len * sizeof(int));    memcpy(p, src, len * sizeof(int));    return p; }
