```{index} single: sv_refcnt; B function ``` ```{index} single: B::sv_refcnt; Perl function ``` # sv_refcnt Return the reference count of the wrapped SV. ## Synopsis ```perl my $sv = B::svref_2object(\$x); print $sv->REFCNT; ``` Calling `REFCNT` does not itself alter the count the `B::*` wrapper reports (the wrapper holds a weak handle, not a strong reference).
