how is dup/ref-counting handled in openssl?

[sd dd]

so in window crypto api, there is this concept of duplicate and ref counting, 
for example, CertDuplicateStore call basically increments the store ref count.

 

i am wondering if openssl handles this? how do i understand the concept openssl 
uses? ( right now my understanding is there is no such thing in openssl)

 

thanks,
