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\-2020 The OpenSSL Project Authors.
