.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fB\s-1BIO_ADDR\s0\fR type is a wrapper around all types of socket
addresses that OpenSSL deals with, currently transparently
supporting \s-1AF_INET, AF_INET6\s0 and \s-1AF_UNIX\s0 according to what's
available on the platform at hand.
.PP
\&\fBBIO_ADDR_new()\fR creates a new unfilled \fB\s-1BIO_ADDR\s0\fR, to be used
with routines that will fill it with information, such as
\&\fBBIO_accept_ex()\fR.
.PP
\&\fBBIO_ADDR_free()\fR frees a \fB\s-1BIO_ADDR\s0\fR created with \fBBIO_ADDR_new()\fR.
.PP
\&\fBBIO_ADDR_clear()\fR clears any data held within the provided \fB\s-1BIO_ADDR\s0\fR and sets
it back to an uninitialised state.
.PP
\&\fBBIO_ADDR_rawmake()\fR takes a protocol \fBfamily\fR, a byte array of
size \fBwherelen\fR with an address in network byte order pointed at
by \fBwhere\fR and a port number in network byte order in \fBport\fR (except
for the \fB\s-1AF_UNIX\s0\fR protocol family, where \fBport\fR is meaningless and
therefore ignored) and populates the given \fB\s-1BIO_ADDR\s0\fR with them.
In case this creates a \fB\s-1AF_UNIX\s0\fR \fB\s-1BIO_ADDR\s0\fR, \fBwherelen\fR is expected
to be the length of the path string (not including the terminating
\&\s-1NUL,\s0 such as the result of a call to \fBstrlen()\fR).
\&\fIRead on about the addresses in \*(L"\s-1RAW ADDRESSES\*(R"\s0 below\fR.
.PP
\&\fBBIO_ADDR_family()\fR returns the protocol family of the given
\&\fB\s-1BIO_ADDR\s0\fR. The possible non-error results are one of the
constants \s-1AF_INET, AF_INET6\s0 and \s-1AF_UNIX.\s0 It will also return \s-1AF_UNSPEC\s0 if the
\&\s-1BIO_ADDR\s0 has not been initialised.
.PP
\&\fBBIO_ADDR_rawaddress()\fR will write the raw address of the given
\&\fB\s-1BIO_ADDR\s0\fR in the area pointed at by \fBp\fR if \fBp\fR is non-NULL,
and will set \fB*l\fR to be the amount of bytes the raw address
takes up if \fBl\fR is non-NULL.
A technique to only find out the size of the address is a call
with \fBp\fR set to \fB\s-1NULL\s0\fR. The raw address will be in network byte
order, most significant byte first.
In case this is a \fB\s-1AF_UNIX\s0\fR \fB\s-1BIO_ADDR\s0\fR, \fBl\fR gets the length of the
path string (not including the terminating \s-1NUL,\s0 such as the result of
a call to \fBstrlen()\fR).
\&\fIRead on about the addresses in \*(L"\s-1RAW ADDRESSES\*(R"\s0 below\fR.
.PP
\&\fBBIO_ADDR_rawport()\fR returns the raw port of the given \fB\s-1BIO_ADDR\s0\fR.
The raw port will be in network byte order.
.PP
\&\fBBIO_ADDR_hostname_string()\fR returns a character string with the
hostname of the given \fB\s-1BIO_ADDR\s0\fR. If \fBnumeric\fR is 1, the string
will contain the numerical form of the address. This only works for
\&\fB\s-1BIO_ADDR\s0\fR of the protocol families \s-1AF_INET\s0 and \s-1AF_INET6.\s0 The
returned string has been allocated on the heap and must be freed
with \fBOPENSSL_free()\fR.
.PP
\&\fBBIO_ADDR_service_string()\fR returns a character string with the
service name of the port of the given \fB\s-1BIO_ADDR\s0\fR. If \fBnumeric\fR
is 1, the string will contain the port number. This only works
for \fB\s-1BIO_ADDR\s0\fR of the protocol families \s-1AF_INET\s0 and \s-1AF_INET6.\s0 The
returned string has been allocated on the heap and must be freed
with \fBOPENSSL_free()\fR.
.PP
\&\fBBIO_ADDR_path_string()\fR returns a character string with the path
of the given \fB\s-1BIO_ADDR\s0\fR. This only works for \fB\s-1BIO_ADDR\s0\fR of the
protocol family \s-1AF_UNIX.\s0 The returned string has been allocated
on the heap and must be freed with \fBOPENSSL_free()\fR.
.SH "RAW ADDRESSES"
.IX Header "RAW ADDRESSES"
Both \fBBIO_ADDR_rawmake()\fR and \fBBIO_ADDR_rawaddress()\fR take a pointer to a
network byte order address of a specific site. Internally, those are
treated as a pointer to \fBstruct in_addr\fR (for \fB\s-1AF_INET\s0\fR), \fBstruct
in6_addr\fR (for \fB\s-1AF_INET6\s0\fR) or \fBchar *\fR (for \fB\s-1AF_UNIX\s0\fR), all
depending on the protocol family the address is for.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
The string producing functions \fBBIO_ADDR_hostname_string()\fR,
\&\fBBIO_ADDR_service_string()\fR and \fBBIO_ADDR_path_string()\fR will
return \fB\s-1NULL\s0\fR on error and leave an error indication on the
OpenSSL error stack.
.PP
All other functions described here return 0 or \fB\s-1NULL\s0\fR when the
information they should return isn't available.
