       issue on GitHub at https://github.com/obgm/libcoap/issues

       The CoAP libcoap logic needs to be initialized before there is any use of the libcoap public API. This is
       done by calling coap_startup().

Function:coap_startup()

       The coap_startup() function must be called before any other coap_*() functions are called. It is used to
       initialize things like mutexes, random number gererators, clocks, TLS libraries etc.

       NOTE: This should be called after any other lower layer is initialized. For example, for LwIP,
       lwip_init() must be called before coap_startup().

       NOTE: After the inital call to coap_startup(), subsequent calls are ignored until coap_cleanup() is
       called.

       Function:coap_cleanup()

       The coap_cleanup() function is used to cleanup / free any information set up by the coap_startup()
       function and should be the last coap_*() function called. It is possible to call coap_startup() after
       coap_cleanup() to re-initialize the libcoap logic.

       NOTE: All other libcoap cleanups should called prior to coap_cleanup(), e.g. coap_free_context(3).

       For specific (D)TLS library support, link with -lcoap-3-notls, -lcoap-3-gnutls, -lcoap-3-openssl,
       -lcoap-3-mbedtls or -lcoap-3-tinydtls. Otherwise, link with -lcoap-3 to get the default (D)TLS library
       support.
