Summary : Additional B helpers to check Copy On Write status
URL : https://metacpan.org/release/B-COW
License : GPL+ or Artistic
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.
