malloc, once again

I have a struct like
typedef struct { char* dildo; int etc } anus;.
Later on I want to make an anus array, with dildo being a string entered by the user.
Now how do I reserve the memory for dildo in my anus array?

So far I have:

typedef struct { char* dildo; int etc } anus;
...
char* small_dildo = fancy_input_routine();
anus* anii = (anus*) malloc(array_size * sizeof(anus));
With that I can't memcpy any small_dildo into my anii obviously, however I'm not quite sure how to do it.

For example, if I were to design a computer from scratch, I'd go with 18 bit bytes, mapping one character to one byte, and creating UTF-18 for it (fixed size, just a remap of UTF-32).
