+=head1 NAME
+
+BIO_socket, BIO_connect, BIO_listen, BIO_accept_ex, BIO_closesocket - BIO
+socket communication setup routines
+
+=head1 SYNOPSIS
+
+ #include <openssl/bio.h>
+
+ int BIO_socket(int domain, int socktype, int protocol, int options);
+ int BIO_connect(int sock, const BIO_ADDR *addr, int options);
+ int BIO_listen(int sock, const BIO_ADDR *addr, int options);
+ int BIO_accept_ex(int accept_sock, BIO_ADDR *peer, int options);
+ int BIO_closesocket(int sock);
+
+=head1 DESCRIPTION
+
+BIO_socket() creates a socket in the domain B<domain>, of type
+B<socktype> and B<protocol>.  Socket B<options> are currently unused,
+but is present for future use.
+
+BIO_connect() connects B<sock> to the address and service given by
+B<addr>.  Connection B<options> may be zero or any combination of
+B<BIO_SOCK_KEEPALIVE>, B<BIO_SOCK_NONBLOCK> and B<BIO_SOCK_NODELAY>.
+The flags are described in L</FLAGS> below.
+
+BIO_listen() has B<sock> start listening on the address and service
+given by B<addr>.  Connection B<options> may be zero or any
+combination of B<BIO_SOCK_KEEPALIVE>, B<BIO_SOCK_NONBLOCK>,
+B<BIO_SOCK_NODELAY>, B<BIO_SOCK_REUSEADDR> and B<BIO_SOCK_V6_ONLY>.
+The flags are described in L</FLAGS> below.
+
+BIO_accept_ex() waits for an incoming connections on the given
+socket B<accept_sock>.  When it gets a connection, the address and
+port of the peer gets stored in B<peer> if that one is non-NULL.
+Accept B<options> may be zero or B<BIO_SOCK_NONBLOCK>, and is applied
+on the accepted socket.  The flags are described in L</FLAGS> below.
+
+BIO_closesocket() closes B<sock>.
+
+=head1 FLAGS
+
+=over 4
+
+=item BIO_SOCK_KEEPALIVE
+
+Enables regular sending of keep-alive messages.
+
+=item BIO_SOCK_NONBLOCK
+
+Sets the socket to non-blocking mode.
+
+=item BIO_SOCK_NODELAY
+
+Corresponds to B<TCP_NODELAY>, and disables the Nagle algorithm.  With
+this set, any data will be sent as soon as possible instead of being
+buffered until there's enough for the socket to send out in one go.
+
+=item BIO_SOCK_REUSEADDR
+
+Try to reuse the address and port combination for a recently closed
+port.
+
+=item BIO_SOCK_V6_ONLY
+
+When creating an IPv6 socket, make it only listen for IPv6 addresses
+and not IPv4 addresses mapped to IPv6.
+
+=back
+
+These flags are bit flags, so they are to be combined with the
+C<|> operator, for example:
+
+  BIO_connect(sock, addr, BIO_SOCK_KEEPALIVE | BIO_SOCK_NONBLOCK);
+
+=head1 RETURN VALUES
+
+BIO_socket() returns the socket number on success or B<INVALID_SOCKET>
+(-1) on error.  When an error has occurred, the OpenSSL error stack
+will hold the error data and errno has the system error.
+
+BIO_connect() and BIO_listen() return 1 on success or 0 on error.
+When an error has occurred, the OpenSSL error stack will hold the error
+data and errno has the system error.
+
+BIO_accept_ex() returns the accepted socket on success or
+B<INVALID_SOCKET> (-1) on error.  When an error has occurred, the
+OpenSSL error stack will hold the error data and errno has the system
+error.
+
+=head1 HISTORY
+
+BIO_gethostname(), BIO_get_port(), BIO_get_host_ip(),
+BIO_get_accept_socket() and BIO_accept() are deprecated since OpenSSL
+1.1.  Use the functions described above instead.
