.ie n .SS "Why does $resolver\->\fIquery()\fP return undef when the answer section is empty?"
.el .SS "Why does \f(CW$resolver\fP\->\fIquery()\fP return undef when the answer section is empty?"
.IX Subsection "Why does $resolver->query() return undef when the answer section is empty?"
The short answer is, do not use \fIquery()\fR.
\&\f(CW$resolver\fR\->\fIsend()\fR will always return the answer packet,
as long as an answer was received.
.PP
The longer answer is that \fIquery()\fR is modeled after the \fIres_query()\fR function
from the libresolv C library, which has similar behavior.
