Topic: Unable to compile src/io

The compiler stops with an error in src/io.
The error is in function EmbedReceiveFrom at line 403 with the error message storage size of ' peer' isn't known.
I also get the same error in function EmbedGenerateCookie and a warning "unused variable 'peer'.
How do I reconcile this error?

Re: Unable to compile src/io

Hi Will,

The EmbedReceiveFrom and EmbedGenerateCookie functions are for DTLS (with WOLFSSL_DTLS defined). The "struct sockaddr_storage" is a POSIX compliant data type for UDP.

If you are using DTLS and called wolfSSL_CTX_new with a wolfDTLSv1_2_client_method or wolfDTLSv1_client_method then you'll want to implement your own IO callbacks for the read/writes.

To do this define WOLFSSL_USER_IO and set the callbacks using wolfSSL_SetIORecv, wolfSSL_SetIOSend and wolfSSL_set_fd. A good example for this is here:
https://github.com/wolfSSL/wolfssl-exam … ack.c#L182

Let me know if you have any other questions or issues.

Thanks,
David Garske, wolfSSL
