=for apidoc m|void|SAVEPADSV |PADOFFSET po
Save a pad slot (used to restore after an iteration)
=cut
XXX DAPM it would make more sense to make the arg a PADOFFSET
=for apidoc m|void|SAVECLEARSV |SV **svp
Clear the pointed to pad value on scope exit. (i.e. the runtime action of
C<my>)
=for apidoc m|void|SAVECOMPPAD
save C<PL_comppad> and C<PL_curpad>
=for apidoc Amx|PAD **|PadlistARRAY|PADLIST * padlist
The C array of a padlist, containing the pads. Only subscript it with
numbers >= 1, as the 0th entry is not guaranteed to remain usable.
=for apidoc Amx|SSize_t|PadlistMAX|PADLIST * padlist
The index of the last allocated space in the padlist. Note that the last
pad may be in an earlier slot. Any entries following it will be C<NULL> in
that case.
=for apidoc Amx|PADNAMELIST *|PadlistNAMES|PADLIST * padlist
The names associated with pad entries.
=for apidoc Amx|PADNAME **|PadlistNAMESARRAY|PADLIST * padlist
The C array of pad names.
=for apidoc Amx|SSize_t|PadlistNAMESMAX|PADLIST * padlist
The index of the last pad name.
=for apidoc Amx|U32|PadlistREFCNT|PADLIST * padlist
The reference count of the padlist. Currently this is always 1.
=for apidoc Amx|PADNAME **|PadnamelistARRAY|PADNAMELIST * pnl
The C array of pad names.
=for apidoc Amx|SSize_t|PadnamelistMAX|PADNAMELIST * pnl
The index of the last pad name.
=for apidoc Amx|SSize_t|PadnamelistREFCNT|PADNAMELIST * pnl
The reference count of the pad name list.
=for apidoc Amx|void|PadnamelistREFCNT_dec|PADNAMELIST * pnl
Lowers the reference count of the pad name list.
=for apidoc Amx|SV **|PadARRAY|PAD * pad
The C array of pad entries.
=for apidoc Amx|SSize_t|PadMAX|PAD * pad
The index of the last pad entry.
=for apidoc Amx|char *|PadnamePV|PADNAME * pn
The name stored in the pad name struct. This returns C<NULL> for a target
slot.
=for apidoc Amx|STRLEN|PadnameLEN|PADNAME * pn
The length of the name.
=for apidoc Amx|bool|PadnameUTF8|PADNAME * pn
Whether PadnamePV is in UTF-8. Currently, this is always true.
=for apidoc Amx|SV *|PadnameSV|PADNAME * pn
Returns the pad name as a mortal SV.
=for apidoc m|bool|PadnameIsOUR|PADNAME * pn
Whether this is an "our" variable.
=for apidoc m|HV *|PadnameOURSTASH|PADNAME * pn
The stash in which this "our" variable was declared.
=for apidoc m|bool|PadnameOUTER|PADNAME * pn
Whether this entry belongs to an outer pad. Entries for which this is true
are often referred to as 'fake'.
=for apidoc m|bool|PadnameIsSTATE|PADNAME * pn
Whether this is a "state" variable.
=for apidoc m|bool|PadnameIsFIELD|PADNAME * pn
Whether this is a "field" variable. PADNAMEs where this is true will
have additional information available via C<PadnameFIELDINFO>.
=for apidoc m|HV *|PadnameTYPE|PADNAME * pn
The stash associated with a typed lexical. This returns the C<%Foo::> hash
for C<my Foo $bar>.
=for apidoc Amx|SSize_t|PadnameREFCNT|PADNAME * pn
The reference count of the pad name.
=for apidoc Amx|PADNAME *|PadnameREFCNT_inc|PADNAME * pn
Increases the reference count of the pad name. Returns the pad name itself.
=for apidoc Amx|void|PadnameREFCNT_dec|PADNAME * pn
Lowers the reference count of the pad name.
=for apidoc m|SV *|PAD_SETSV |PADOFFSET po|SV* sv
Set the slot at offset C<po> in the current pad to C<sv>
=for apidoc m|SV *|PAD_SV |PADOFFSET po
Get the value at offset C<po> in the current pad
=for apidoc m|SV *|PAD_SVl |PADOFFSET po
Lightweight and lvalue version of C<PAD_SV>.

Get the value from slot C<po> in the base (DEPTH=1) pad of a padlist
=for apidoc m|void|PAD_SET_CUR |PADLIST padlist|I32 n
Set the current pad to be pad C<n> in the padlist, saving
the previous current pad. NB currently this macro expands to a string too
long for some compilers, so it's best to replace it with
SAVECOMPPAD();
PAD_SET_CUR_NOSAVE(padlist,n);
=for apidoc m|void|PAD_SET_CUR_NOSAVE |PADLIST padlist|I32 n
like PAD_SET_CUR, but without the save
=for apidoc m|void|PAD_SAVE_SETNULLPAD
Save the current pad then set it to null.
=for apidoc m|void|PAD_SAVE_LOCAL|PAD *opad|PAD *npad
Save the current pad to the local variable C<opad>, then make the
current pad equal to C<npad>
=for apidoc m|void|PAD_RESTORE_LOCAL|PAD *opad
Restore the old pad saved into the local variable C<opad> by C<PAD_SAVE_LOCAL()>
