15 This file is the autogenerated documentation of functions in
16 the Perl interpreter that are documented using Perl's
17 internal documentation format but are not marked as part of
18 the Perl API . In other words, __they are
19 not for use in extensions__!

25 Returns TRUE if given the name of a magical

52 When Perl is run in debugging mode, with the __-d__
53 switch, this SV is a boolean which indicates
54 whether subs are being single-stepped. Single-stepping is
55 automatically turned on after every step. This is the C
56 variable which corresponds to Perl's $DB::single
57 variable. See PL_DBsub.
