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. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBBIO_connect\fR\|(3), \fBBIO_s_connect\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016\-2020 The OpenSSL Project Authors.
