160In all these calls, the C<U32 wI<n>> parameters are warning category
161constants. You can see the ones currently available in
162L<warnings/Category Hierarchy>, just capitalize all letters in the names
163and prefix them by C<WARN_>. So, for example, the category C<void> used in a
164perl program becomes C<WARN_VOID> when used in XS code and passed to one of
165the calls below.

193These macros are used to pack warning categories into a single U32 to pass to
194macros and functions that take a warning category parameter. The number of
195categories to pack is given by the name, with a corresponding number of
196category parameters passed.
