115 This flag, used in the length slot of hash entries and magic structures,
130 Returns the actual pointer stored in the key slot of the hash entry. The
142 Returns the value slot (type C<SV*>) stored in the hash entry.
145 Returns the computed hash stored in the hash entry.
148 Returns the key slot of the hash entry as a C<char*> value, doing any
153 variable. Remember though, that hash keys in perl are free to contain
155 the length of hash keys. This is very similar to the C<SvPV()> macro
159 Returns the key as an C<SV*>, or C<Nullsv> if the hash entry does not
164 C<SV*> if the hash entry contains only a C<char*> key.
