237 In all these calls, the C<U32 wI<n>> parameters are warning category
238 constants. You can see the ones currently available in
239 L<warnings/Category Hierarchy>, just capitalize all letters in the names
240 and prefix them by C<WARN_>. So, for example, the category C<void> used in a
241 perl program becomes C<WARN_VOID> when used in XS code and passed to one of
244 =for apidoc Am|bool|ckWARN|U32 w
245 =for apidoc_item ||ckWARN2|U32 w1|U32 w2
246 =for apidoc_item ||ckWARN3|U32 w1|U32 w2|U32 w3
247 =for apidoc_item ||ckWARN4|U32 w1|U32 w2|U32 w3|U32 w4
248 These return a boolean as to whether or not warnings are enabled for any of
249 the warning category(ies) parameters: C<w>, C<w1>, ....
251 Should any of the categories by default be enabled even if not within the
252 scope of S<C<use warnings>>, instead use the C<L</ckWARN_d>> macros.
254 The categories must be completely independent, one may not be subclassed from

260 =for apidoc_item ||ckWARN4_d|U32 w1|U32 w2|U32 w3|U32 w4
262 Like C<L</ckWARN>>, but for use if and only if the warning category(ies) is by
263 default enabled even if not within the scope of S<C<use warnings>>.

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