DTLS example out of date? #88

Closed ptone closed 7 years ago

ptone commented 7 years ago

The current DTLS sample uses:

req := canopus.NewRequest(canopus.MessageConfirmable, canopus.Get, canopus.GenerateMessageID())

Which gives:

# command-line-arguments ./client.go:15: too many arguments in call to canopus.NewRequest have (number, canopus.CoapCode, uint16) want (uint8, canopus.CoapCode)

The "simple" example, which works, has:

req := canopus.NewRequest(canopus.MessageConfirmable, canopus.Get)

But updating the dtls example to use the same NewRequest syntax results in: `[signal SIGSEGV: segmentation violation code=0x1 addr=0xe0 pc=0x7f12183f3c1b]

Interestingly - I was able to get the updated syntax to work when I rebuilt the libssl.so from the OpenSSL_1_1_0-stable openssl branch
