The file contains porting layer for ssl functionality.
Methods for SSL/TLS protocol Library always calls iotcs_port_ssl_init before start using port SSL API and iotcs_port_ssl_finalize when has stopped using port SSL API.
Port SSL API always shall support at least one SSL connection. Library works with this connection by calling blocking methods iotcs_port_ssl_connect, iotcs_port_ssl_write, iotcs_port_ssl_read, iotcs_port_ssl_disconnect. This is the order in which library calls those methods. The whole connect/write/read/disconnect sequence is invoked from one thread and always exclusively. It means that implementation does not require thread safety.
Library could be built with long polling support by defining IOTCS_LONG_POLLING. Without long polling support library use just one SSL connection at a time. Long polling support adds another connection. Methods that work with this long polling connection have _lp suffix, e.g. iotcs_port_ssl_connect_lp. The whole connect/write/read/disconnect sequence for long polling connection is invoked from one thread and always exclusively. But usual connection and long polling connection could be used by library at same time from different threads.
