The foreign

to check.
.SH "DESCRIPTION"
.PP
Returns true if the foreign pointer is NULL. This is useful in testing whether a foreign function returns something valid,
before throwing an exception. This is the only way, in general, that
\fBPtr \fP
should be queried in Kaya; usually it is better to manipulate
pointers C side.
