DTLSv1_listen Nonblock IO failure not returning SSL_ERROR_WANT_READ

[Raja Ashok <rashok.svks@xxxxxxxxx>]

Hi,

When Nonblock IO failure happens on DTLSv1_listen() its returning 0. But SSL_get_error() is not returning SSL_ERROR_WANT_READ. Instead it returns SSL_ERROR_SYSCALL. 

Can someone tell its intentionally kept this behaviour ?

Thanks & Regards,
