Thanks for pointing out to the C file, but as these these system calls 
can support only synchronous operations, precludes their use for 
asynchronous operations. In the TLS handshakes, where multiple 
connections occur simultaneously, asynchronous operations are 
beneficial. OpenSSL ASYNC support can very well utilizes the 
asynchronous operations while establishing multiple TLS connections.

Thanks,
Nipun
