.SH NAME
shishi_realm_default_guess \- API function
.SH SYNOPSIS
.B #include <shishi.h>
.sp
.BI "char * shishi_realm_default_guess();"
.SH "DESCRIPTION"
Guesses a realm based on \fBgetdomainname()\fP, which really responds
with a NIS/YP domain, but if set properly, it might be a good
first guess.  If this NIS query fails, call \fBgethostname()\fP,
and on its failure, fall back to returning the artificial
string "could\-not\-guess\-default\-realm".

Note that the hostname is not trimmed off of the string returned
by \fBgethostname()\fP, thus pretending the local host name is a valid
realm name.  The resulting corner case could merit a check that
the suggested realm is distinct from the fully qualifies host,
and if not, simply strip the host name from the returned string
before it is used in an application.  One reason for sticking
with the present behaviour, is that some systems respond with
a non\-qualified host name as reply from \fBgethostname()\fP.
.SH "RETURN VALUE"
Returns a guessed realm for the running host,
containing a string that has to be deallocated with
\fBfree()\fP by the caller.
.SH "REPORTING BUGS"
Report bugs to <bug-shishi@gnu.org>.
