| Summary : Additional B helpers to check Copy On Write status
|
Description :
B::COW provides some naïve additional B helpers to check the Copy On Write
(COW) status of one SvPV (a Perl string variable).
A COWed SvPV is sharing its string (the PV) with other SvPVs. It\'s a (kind of)
Read Only C string, which would be Copied On Write (COW). More than one SV can
share the same PV, but when one PV needs to alter it, it would perform a copy
of it, decreasing the COWREFCNT counter. One SV can then drop the COW flag when
it\'s the only one holding a pointer to the PV. The COWREFCNT is stored at the
end of the PV, after the null byte terminating the string. That value is
limited to 255: when we reach 255, a new PV would be created.
