Hi,
As a temporary workaround for the you can use:
ssl.MBEDTLS_PRIVATE(handshake).resume
But please be aware that this is something that could break with any future release, so should only be used as a very temporary workaround.
We made these members private in 3.0.0, and thus need to know if anyone's code paths have been broken as a result, so we can add accessors or new methods as required. Regarding this, may I enquire the reason for your needing to know if the session has been resumed - is this only a debug thing, or do you have a requirement in your codebase to know this?
Regards,
Paul.

I am trying to modify the dtls_server.c example to keep track of whether session caching was used for a given connection.
Ideally I would have an interget value i.e `session_resumed = #1 or 0`
One way I tried to do this was by reading the value of the mbedtls_ssl_context struct `ssl`:
/* * 5. Handshake */ do ret = mbedtls_ssl_handshake( &ssl ); while( ret == MBEDTLS_ERR_SSL_WANT_READ || ret == MBEDTLS_ERR_SSL_WANT_WRITE ); if( ret == MBEDTLS_ERR_SSL_HELLO_VERIFY_REQUIRED ) { printf( " hello verification requested\n" ); ret = 0; goto reset; } else if( ret != 0 ) { printf( " failed\n ! mbedtls_ssl_handshake returned - 0x%x\n\n", (unsigned int) -ret ); goto reset; } printf( " session cache status: %d\n", ssl.handshake.resume );The issue with this is that the ssl struct is set to private, so the code fails to compile with the error: 'struct mbedtls_ssl_context' has no member named 'handshake'
Can somebody help me with some example code that would make this possible?
