port. The port is represented as a string of the form "host:port",
where "host" is the interface to use and "port" is the port.
The host can be "*" or empty which is interpreted as meaning
-any interface. If the host is a IPv6 address, it has to be
+any interface. If the host is an IPv6 address, it has to be
enclosed in brackets, for example "[::1]:https". "port" has the
same syntax as the port specified in BIO_set_conn_port() for
connect BIOs, that is it can be a numerical port string or a
BIO_set_accept_bios() can be used to set a chain of BIOs which
will be duplicated and prepended to the chain when an incoming
-connection is received. This is useful if, for example, a
+connection is received. This is useful if, for example, a
buffering or SSL BIO is required for each connection. The
chain of BIOs must not be freed after this call, they will
be automatically freed when the accept BIO is freed.
