c - using memcpy to copy a structure -

possible duplicates:
copying 1 structure another
copying 1 structure another

       struct node         {            int n;             struct classifier keys[m-1];            struct node *p[m];         }*root=null;

i have created newnode of type node

        (*newnode)->keys[i]

i want copy data keys structure structure clsf_ptr of same type can this,i don't want initialize each member function

       memcpy((*newnode)->keys[i], clsf_ptr)

for start, should be:

memcpy(&(newnode->keys[i]), &clsf_ptr, sizeof(struct classifier));

(assuming newnode pointer-to-node, , clsf_ptr classifier`).

also, struct assignment legal in c, do:

newnode->keys[i] = clsf_ptr;

note both of these approaches shallow copy. if struct classifier has pointers memory, pointers copied, rather creating new copies of memory.
