typedef struct nng_tls_engine_s nng_tls_engine;
The TLS engine API is provided for developers wishing to implement their own implementation of TLS, or to adapt a 3rd party TLS implementation to the work with NNG.
At this time, there is no further documentation on implementing a TLS
engine oneself, but existing source code may be a guide.
The primary interfaces are located in the
<nng/supplemental/tls/engine.h> header file.
