.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Stringification of flags.
.PP
By default, \f(CW\*(C`$foo\->flags\*(C'\fR when passed an object in the \f(CW\*(C`B\*(C'\fR class
will produce a relatively meaningless number, which one would need to
grovel through the Perl source code in order to do anything useful with.
This module adds \f(CW\*(C`flagspv\*(C'\fR to the \s-1SV\s0 and op classes and \f(CW\*(C`privatepv\*(C'\fR to
the op classes, which makes them easier to understand.
.SH "METHODS"
.IX Header "METHODS"
.IP "\s-1OP\-\s0>flagspv" 4
.IX Item "OP->flagspv"
Returns stringification of the \s-1OP\s0 flags.
.Sp
Adds now \s-1SIBLING\s0 to abstract the new \s-1LASTSIB/MORESIB\s0 flags since 5.21/5.22
and the old \f(CW\*(C`op_sibling\*(C'\fR pointer. Since 5.22 missing the \s-1SIBLING\s0 flags indicates
a \s-1PARENT\s0 at the \f(CW\*(C`op_sibparent\*(C'\fR pointer, with \-DPERL_OP_PARENT.
.IP "\s-1OP\-\s0>privatepv" 4
.IX Item "OP->privatepv"
Returns stringification of the \s-1OP\s0 private flags.
.IP "\s-1SV\-\s0>flagspv [type]" 4
.IX Item "SV->flagspv [type]"
Returns stringification of the \s-1SV\s0 flags.
.Sp
With the optional type only the flags for the given SvTYPE are used.
type 0 is for the SvFLAGS only.
This way you can seperate between sv\->\s-1FLAGS\s0 and specialized AvFLAGS,
GvFLAGS, CvFLAGS, ... in seperate struct fields.
.Sp
Note that only the names of bitmasked \s-1SV\s0 and \s-1OP\s0 flags are returned,
not pseudo flags, like \s-1TAINTED,\s0 which is stored as magic.
\&\s-1PAD, PADNAME, PADLIST\s0 and \s-1PADNAMELIST\s0 flags are now also supported.
