C structure Replication

I have encountered a problem some time ago. I 'd like to share it with you.

When writing code, the structure replication problem occurs. That is, the variable values in a structure are completely copied to another structure with the same structure.

I used memcpy, and found that after the copy, the variable value in the new struct still does not exist, and can only replicate a single variable.

It is worth noting that my struct contains pointer variables, so during replication, we need to open up a new space for it to be copied separately.

If you have a good structure COPY method (containing pointers), please let me know. O (struct _ pointer) O
