-sv_magic()
-----------
-av.c
-av_store()
- Storing a non-undef element into an SMAGICAL array, av,
- assigns the equivalent lowercase form of magic (of the first
- MAGIC in the chain) to the value (with obj = av, name = 0 and
- namlen = array index).
-
-gv.c
-gv_init()
- Initialising gv assigns '*' magic to it with obj = gv, name =
- GvNAME and namlen = GvNAMELEN.
-gv_fetchpv()
- @ISA gets 'I' magic with obj = gv, zero name and namlen.
- %OVERLOAD gets 'A' magic with obj = gv, zero name and namlen.
- $1 to $9, $&, $`, $', $+ get '\0' magic with obj = gv,
- name = GvNAME and namlen = len ( = 1 presumably).
-Gv_AMupdate()
- Stashes for overload magic seem to get 'c' magic with obj = 0,
- name = &amt and namlen = sizeof(amt).
-hv_magic(hv, gv, how)
- Gives magic how to hv with obj = gv and zero name and namlen.
-
-mg.c
-mg_copy(sv, nsv, key, klen)
- Traverses the magic chain of sv. Upper case forms of magic
- (only) are copied across to nsv, preserving obj but using
- name = key and namlen = klen.
-magic_setpos()
- LvTARG of a PVLV gets 'g' magic with obj = name = 0 and namlen = pos.
-
-op.c
-mod()
- PVLV operators give magic to their targs with
- obj = name = namlen = 0. OP_POS gives '.', OP_VEC gives 'v'
- and OP_SUBSTR gives 'x'.
-
-perl.c
-magicname(sym, name, namlen)
- Fetches/creates a GV with name sym and gives it '\0' magic
- with obj = gv, name and namlen as passed.
-init_postdump_symbols()
- Elements of the environment get given SVs with 'e' magic.
- obj = sv and name and namlen point to the actual string
- within env.
-
-pp.c
-pp_av2arylen()
- $#foo gives '#' magic to the new SV with obj = av and
- name = namlen = 0.
-pp_study()
- SV gets 'g' magic with obj = name = namlen = 0.
-pp_substr()
- PVLV gets 'x' magic with obj = name = namlen = 0.
-pp_vec()
- PVLV gets 'x' magic with obj = name = namlen = 0.
-
-pp_hot.c
-pp_match()
- m//g gets 'g' magic with obj = name = namlen = 0.
-
-pp_sys.c
-pp_tie()
- sv gets magic with obj = sv and name = namlen = 0.
- If an HV or an AV, it gets 'P' magic, otherwise 'q' magic.
-pp_dbmopen()
- 'P' magic for the HV just as with pp_tie().
-pp_sysread()
- If tainting, the buffer SV gets 't' magic with
- obj = name = namlen = 0.
-
-sv.c
-sv_setsv()
- Doing sv_setsv(dstr, gv) gives '*' magic to dstr with
- obj = dstr, name = GvNAME, namlen = GvNAMELEN.
-
-util.c
-fbm_compile()
- The PVBM gets 'B' magic with obj = name = namlen = 0 and SvVALID
- is set to indicate that the Boyer-Moore table is valid.
- magic_setbm() just clears the SvVALID flag.
-
-hv_magic()
-----------
-
-gv.c
-gv_fetchfile()
- With perldb, the HV of a gvfile gv gets 'L' magic with obj = gv.
-gv_fetchpv()
- %SIG gets 'S' magic with obj = siggv.
-init_postdump_symbols()
- %ENV gets 'E' magic with obj = envgv.
