=pod =head1 NAME BIO_hostserv_priorities, BIO_parse_hostserv - utility routines to parse a standard host and service string =head1 SYNOPSIS #include enum BIO_hostserv_priorities { BIO_PARSE_PRIO_HOST, BIO_PARSE_PRIO_SERV }; int BIO_parse_hostserv(const char *hostserv, char **host, char **service, enum BIO_hostserv_priorities hostserv_prio); =head1 DESCRIPTION BIO_parse_hostserv() will parse the information given in B, create strings with the host name and service name and give those back via B and B. Those will need to be freed after they are used. B helps determine if B shall be interpreted primarily as a host name or a service name in ambiguous cases. The syntax the BIO_parse_hostserv() recognises is: host + ':' + service host + ':' + '*' host + ':' ':' + service '*' + ':' + service host service The host part can be a name or an IP address. If it's a IPv6 address, it MUST be enclosed in brackets, such as '[::1]'. The service part can be a service name or its port number. The returned values will depend on the given B string and B, as follows: host + ':' + service => *host = "host", *service = "service" host + ':' + '*' => *host = "host", *service = NULL host + ':' => *host = "host", *service = NULL ':' + service => *host = NULL, *service = "service" '*' + ':' + service => *host = NULL, *service = "service" in case no ':' is present in the string, the result depends on hostserv_prio, as follows: when hostserv_prio == BIO_PARSE_PRIO_HOST host => *host = "host", *service untouched when hostserv_prio == BIO_PARSE_PRIO_SERV service => *host untouched, *service = "service" =head1 SEE ALSO L =head1 COPYRIGHT Copyright 2016 The OpenSSL Project Authors.
