4SYNOPSIS

6 # some ops
7 print B::main_root->flagspv;
8 print B::main_root->privatepv;
9 print $some_b_sv_object->flagspv;

11DESCRIPTION
12 Stringification of flags.
13
14 By default, "$foo->flags" when passed an object in the "B" class will
15 produce a relatively meaningless number, which one would need to grovel
16 through the Perl source code in order to do anything useful with. This
17 module adds "flagspv" to the SV and op classes and "privatepv" to the op
18 classes, which makes them easier to understand.
19
20METHODS
21 OP->flagspv
22 Returns stringification of the OP flags.
23
24 Adds now SIBLING to abstract the new LASTSIB/MORESIB flags since
25 5.21/5.22 and the old "op_sibling" pointer. Since 5.22 missing the
26 SIBLING flags indicates a PARENT at the "op_sibparent" pointer, with
27 -DPERL_OP_PARENT.
28
29 OP->privatepv
30 Returns stringification of the OP private flags.
31
32 SV->flagspv [type]
33 Returns stringification of the SV flags.
34
35 With the optional type only the flags for the given SvTYPE are used.
36 type 0 is for the SvFLAGS only. This way you can seperate between
37 sv->FLAGS and specialized AvFLAGS, GvFLAGS, CvFLAGS, ... in seperate
38 struct fields.
39
40 Note that only the names of bitmasked SV and OP flags are returned,
41 not pseudo flags, like TAINTED, which is stored as magic.
