5 BIO_hostserv_priorities,
7 - utility routines to parse a standard host and service string
11 #include <openssl/bio.h>
13 enum BIO_hostserv_priorities {
14 BIO_PARSE_PRIO_HOST, BIO_PARSE_PRIO_SERV
16 int BIO_parse_hostserv(const char *hostserv, char **host, char **service,
17 enum BIO_hostserv_priorities hostserv_prio);
21 BIO_parse_hostserv() will parse the information given in B<hostserv>,
22 create strings with the host name and service name and give those
23 back via B<host> and B<service>. Those will need to be freed after
24 they are used. B<hostserv_prio> helps determine if B<hostserv> shall
25 be interpreted primarily as a host name or a service name in ambiguous
28 The syntax the BIO_parse_hostserv() recognises is:
38 The host part can be a name or an IP address. If it's a IPv6
39 address, it MUST be enclosed in brackets, such as '[::1]'.
41 The service part can be a service name or its port number.
43 The returned values will depend on the given B<hostserv> string
44 and B<hostserv_prio>, as follows:
46 host + ':' + service => *host = "host", *service = "service"
47 host + ':' + '*' => *host = "host", *service = NULL
48 host + ':' => *host = "host", *service = NULL
49 ':' + service => *host = NULL, *service = "service"
50 '*' + ':' + service => *host = NULL, *service = "service"
52 in case no ':' is present in the string, the result depends on
53 hostserv_prio, as follows:
55 when hostserv_prio == BIO_PARSE_PRIO_HOST
56 host => *host = "host", *service untouched
58 when hostserv_prio == BIO_PARSE_PRIO_SERV
59 service => *host untouched, *service = "service"
63 BIO_parse_hostserv() returns 1 on success or 0 on error.
