Pass a pointer to a function as read-only in C

Question

Just as the title says, can I pass a pointer to a function so it\'s only a copy of the pointer\'s contents? I have to be sure the function doesn\'t edit the contents.

Unless the function takes a const parameter, the only thing you can do is explicitly pass it a copy of your data, perhaps created using memcpy.
