|
\&\fIBIO_parse_hostserv()\fR will parse the information given in \fBhostserv\fR,
|
|
create strings with the hostname and service name and give those
|
|
back via \fBhost\fR and \fBservice\fR. Those will need to be freed after
|
|
they are used. \fBhostserv_prio\fR helps determine if \fBhostserv\fR shall
|
|
be interpreted primarily as a hostname or a service name in ambiguous
|
|
cases.
|
|
.PP
|
|
The syntax the \fIBIO_parse_hostserv()\fR recognises is:
|
|
.PP
|
|
.Vb 7
|
|
\& host + \*(Aq:\*(Aq + service
|
|
\& host + \*(Aq:\*(Aq + \*(Aq*\*(Aq
|
|
\& host + \*(Aq:\*(Aq
|
|
\& \*(Aq:\*(Aq + service
|
|
\& \*(Aq*\*(Aq + \*(Aq:\*(Aq + service
|
|
\& host
|
|
\& service
|
|
.Ve
|
|
.PP
|
|
The host part can be a name or an \s-1IP\s0 address. If it's a IPv6
|
|
address, it \s-1MUST\s0 be enclosed in brackets, such as '[::1]'.
|
|
.PP
|
|
The service part can be a service name or its port number.
|
|
.PP
|
|
The returned values will depend on the given \fBhostserv\fR string
|
|
and \fBhostserv_prio\fR, as follows:
|
|
.PP
|
|
.Vb 5
|
|
\& host + \*(Aq:\*(Aq + service => *host = "host", *service = "service"
|
|
\& host + \*(Aq:\*(Aq + \*(Aq*\*(Aq => *host = "host", *service = NULL
|
|
\& host + \*(Aq:\*(Aq => *host = "host", *service = NULL
|
|
\& \*(Aq:\*(Aq + service => *host = NULL, *service = "service"
|
|
\& \*(Aq*\*(Aq + \*(Aq:\*(Aq + service => *host = NULL, *service = "service"
|
|
\&
|
|
\& in case no \*(Aq:\*(Aq 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"
