Openssl bio example
WebOpenSSL comes with a number of useful BIO types predefined, or you can create your own. BIOs come in two flavors: source/sink, or filter. BIOs can be chained together. Each chain always has exactly one source/sink, but can have any number (zero or more) of filters. Reading from a BIO can be done with Manual:BIO_read (3) and BIO_gets . WebSimple TLS Server.
