.IX Header "DESCRIPTION"
|
|
The \fB\s-1BIO_ADDRINFO\s0\fR type is a wrapper for address information
|
|
types provided on your platform.
|
|
.PP
|
|
\&\fB\s-1BIO_ADDRINFO\s0\fR normally forms a chain of several that can be
|
|
picked at one by one.
|
|
.PP
|
|
\&\fBBIO_lookup_ex()\fR looks up a specified \fBhost\fR and \fBservice\fR, and
|
|
uses \fBlookup_type\fR to determine what the default address should
|
|
be if \fBhost\fR is \fB\s-1NULL\s0\fR. \fBfamily\fR, \fBsocktype\fR and \fBprotocol\fR are used to
|
|
determine what protocol family, socket type and protocol should be used for
|
|
the lookup. \fBfamily\fR can be any of \s-1AF_INET, AF_INET6, AF_UNIX\s0 and
|
|
\&\s-1AF_UNSPEC.\s0 \fBsocktype\fR can be \s-1SOCK_STREAM, SOCK_DGRAM\s0 or 0. 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.
