Specifying 0 +indicates that any type can be used. \fBprotocol\fR specifies a protocol such as +\&\s-1IPPROTO_TCP, IPPROTO_UDP\s0 or \s-1IPPORTO_SCTP.\s0 If set to 0 than any protocol can be +used. \fBres\fR points at a pointer to hold the start of a \fB\s-1BIO_ADDRINFO\s0\fR +chain. +.PP +For the family \fB\s-1AF_UNIX\s0\fR, \fBBIO_lookup_ex()\fR will ignore the \fBservice\fR +parameter and expects the \fBnode\fR parameter to hold the path to the +socket file. +.PP +\&\fBBIO_lookup()\fR does the same as \fBBIO_lookup_ex()\fR but does not provide the ability +to select based on the protocol (any protocol may be returned). +.PP +\&\fBBIO_ADDRINFO_family()\fR returns the family of the given +\&\fB\s-1BIO_ADDRINFO\s0\fR. The result will be one of the constants +\&\s-1AF_INET, AF_INET6\s0 and \s-1AF_UNIX.\s0 +.PP +\&\fBBIO_ADDRINFO_socktype()\fR returns the socket type of the given +\&\fB\s-1BIO_ADDRINFO\s0\fR. The result will be one of the constants +\&\s-1SOCK_STREAM\s0 and \s-1SOCK_DGRAM.\s0 +.PP +\&\fBBIO_ADDRINFO_protocol()\fR returns the protocol id of the given +\&\fB\s-1BIO_ADDRINFO\s0\fR. The result will be one of the constants +\&\s-1IPPROTO_TCP\s0 and \s-1IPPROTO_UDP.\s0 +.PP +\&\fBBIO_ADDRINFO_address()\fR returns the underlying \fB\s-1BIO_ADDR\s0\fR +of the given \fB\s-1BIO_ADDRINFO\s0\fR. +.PP +\&\fBBIO_ADDRINFO_next()\fR returns the next \fB\s-1BIO_ADDRINFO\s0\fR in the chain +from the given one. +.PP +\&\fBBIO_ADDRINFO_free()\fR frees the chain of \fB\s-1BIO_ADDRINFO\s0\fR starting +with the given one. +.SH "RETURN VALUES" +.IX Header "RETURN VALUES" +\&\fBBIO_lookup_ex()\fR and \fBBIO_lookup()\fR return 1 on success and 0 when an error +occurred, and will leave an error indication on the OpenSSL error stack in that +case. +.PP +All other functions described here return 0 or \fB\s-1NULL\s0\fR when the +information they should return isn't available. +.SH "NOTES" +.IX Header "NOTES" +The \fBBIO_lookup_ex()\fR implementation uses the platform provided \fBgetaddrinfo()\fR +function. On Linux it is known that specifying 0 for the protocol will not +return any \s-1SCTP\s0 based addresses when calling \fBgetaddrinfo()\fR. Therefore if an \s-1SCTP\s0 +address is required then the \fBprotocol\fR parameter to \fBBIO_lookup_ex()\fR should be +explicitly set to \s-1IPPROTO_SCTP.\s0 The same may be true on other platforms. +.SH "HISTORY" +.IX Header "HISTORY" +The \fBBIO_lookup_ex()\fR function was added in OpenSSL 1.1.1. +.SH "COPYRIGHT" +.IX Header "COPYRIGHT" +Copyright 2016\-2017 The OpenSSL Project Authors.
