+These return the CV of the specified Perl subroutine. C<flags> are passed to
C<gv_fetchpvn_flags>. If C<GV_ADD> is set and the Perl subroutine does not
exist then it will be declared (which has the same effect as saying
-C<sub name;>). If C<GV_ADD> is not set and the subroutine does not exist
+C<sub name;>). If C<GV_ADD> is not set and the subroutine does not exist,
then NULL is returned.
-=for apidoc get_cv
+The forms differ only in how the subroutine is specified.. With C<get_cvs>,
+the name is a literal C string, enclosed in double quotes. With C<get_cv>, the
+name is given by the C<name> parameter, which must be a NUL-terminated C
+string. With C<get_cvn_flags>, the name is also given by the C<name>
+parameter, but it is a Perl string (possibly containing embedded NUL bytes),
+and its length in bytes is contained in the C<len> parameter.
-Uses C<strlen> to get the length of C<name>, then calls C<get_cvn_flags>.
