NAME

instanceof - check whether an object is an instance of a type

SYNOPSIS

int instanceof(object obj, string type)

DESCRIPTION

Check whether an object is an instance of the given type, which is
first processed by object_type() in the driver object.  The return
value is -1 if the type is privately inherited, 1 if the type is
normally inherited, or 0 otherwise.

ERRORS

An error will result if object_type() does not return a string.

NOTE

instanceof() is not equivalent with <- in the same way as call_other()
is equivalent with ->.  Instanceof processes the type string at
runtime, whereas <- does it at compile time, and masking instanceof()
will not affect <-.
