Socket \fBoptions\fR are currently unused, +but is present for future use. +.PP +\&\fBBIO_bind()\fR binds the source address and service to a socket and +may be useful before calling \fBBIO_connect()\fR. The options may include +\&\fBBIO_SOCK_REUSEADDR\fR, which is described in "FLAGS" below. +.PP +\&\fBBIO_connect()\fR connects \fBsock\fR to the address and service given by +\&\fBaddr\fR. Connection \fBoptions\fR may be zero or any combination of +\&\fBBIO_SOCK_KEEPALIVE\fR, \fBBIO_SOCK_NONBLOCK\fR and \fBBIO_SOCK_NODELAY\fR. +The flags are described in "FLAGS" below. +.PP +\&\fBBIO_listen()\fR has \fBsock\fR start listening on the address and service +given by \fBaddr\fR. Connection \fBoptions\fR may be zero or any +combination of \fBBIO_SOCK_KEEPALIVE\fR, \fBBIO_SOCK_NONBLOCK\fR, +\&\fBBIO_SOCK_NODELAY\fR, \fBBIO_SOCK_REUSEADDR\fR and \fBBIO_SOCK_V6_ONLY\fR. +The flags are described in "FLAGS" below. +.PP +\&\fBBIO_accept_ex()\fR waits for an incoming connections on the given +socket \fBaccept_sock\fR. When it gets a connection, the address and +port of the peer gets stored in \fBpeer\fR if that one is non-NULL. +Accept \fBoptions\fR may be zero or \fBBIO_SOCK_NONBLOCK\fR, and is applied +on the accepted socket. The flags are described in "FLAGS" below. +.PP +\&\fBBIO_closesocket()\fR closes \fBsock\fR. +.SH FLAGS +.IX Header "FLAGS" +.IP BIO_SOCK_KEEPALIVE 4 +.IX Item "BIO_SOCK_KEEPALIVE" +Enables regular sending of keep-alive messages. +.IP BIO_SOCK_NONBLOCK 4 +.IX Item "BIO_SOCK_NONBLOCK" +Sets the socket to nonblocking mode. +.IP BIO_SOCK_NODELAY 4 +.IX Item "BIO_SOCK_NODELAY" +Corresponds to \fBTCP_NODELAY\fR, 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. +.IP BIO_SOCK_REUSEADDR 4 +.IX Item "BIO_SOCK_REUSEADDR" +Try to reuse the address and port combination for a recently closed +port. +.IP BIO_SOCK_V6_ONLY 4 +.IX Item "BIO_SOCK_V6_ONLY" +When creating an IPv6 socket, make it only listen for IPv6 addresses +and not IPv4 addresses mapped to IPv6. +.PP +These flags are bit flags, so they are to be combined with the +\&\f(CW\*(C`|\*(C'\fR operator, for example: +.PP +.Vb 1 +\& BIO_connect(sock, addr, BIO_SOCK_KEEPALIVE | BIO_SOCK_NONBLOCK); +.Ve +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fBBIO_socket()\fR returns the socket number on success or \fBINVALID_SOCKET\fR +(\-1) on error. When an error has occurred, the OpenSSL error stack +will hold the error data and errno has the system error. +.PP +\&\fBBIO_bind()\fR, \fBBIO_connect()\fR and \fBBIO_listen()\fR 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. +.PP +\&\fBBIO_accept_ex()\fR returns the accepted socket on success or +\&\fBINVALID_SOCKET\fR (\-1) on error.
