Yes, you need to make the underlying socket non blocking, and at the same time gotta change the way you call SSL_accept, SSL_read, write etc to handle non block error conditions like want_read, want_write errors, use the code Eric has given to make the fd non block, or u can also set the bio non block by using FIONBIO option. basically you really need to write an asynchronous state machine.
