=head1 NAME perlintern - autogenerated documentation of purely B Perl functions =head1 DESCRIPTION This file is the autogenerated documentation of functions in the Perl interpreter that are documented using Perl's internal documentation format but are not marked as part of the Perl API. In other words, B! =over 8 =item is_gv_magical Returns C if given the name of a magical GV. Currently only useful internally when determining if a GV should be created even in rvalue contexts. C is not used at present but available for future extension to allow selecting particular classes of magical variable. bool is_gv_magical(char *name, STRLEN len, U32 flags) =for hackers Found in file gv.c =item LVRET True if this op will be the return value of an lvalue subroutine =for hackers Found in file pp.h =item PL_DBsingle When Perl is run in debugging mode, with the B<-d> switch, this SV is a boolean which indicates whether subs are being single-stepped. Single-stepping is automatically turned on after every step. This is the C variable which corresponds to Perl's $DB::single variable. See C. SV * PL_DBsingle =for hackers Found in file intrpvar.h =item PL_DBsub When Perl is run in debugging mode, with the B<-d> switch, this GV contains the SV which holds the name of the sub being debugged. This is the C variable which corresponds to Perl's $DB::sub variable. See C. GV * PL_DBsub =for hackers Found in file intrpvar.h =item PL_DBtrace Trace variable used when Perl is run in debugging mode, with the B<-d> switch. This is the C variable which corresponds to Perl's $DB::trace variable. See C. SV * PL_DBtrace =for hackers Found in file intrpvar.h =item PL_dowarn The C variable which corresponds to Perl's $^W warning variable. bool PL_dowarn =for hackers Found in file intrpvar.h =item PL_last_in_gv The GV which was last used for a filehandle input operation. (C<< >>) GV* PL_last_in_gv =for hackers Found in file thrdvar.h =item PL_ofs_sv The output field separator - C<$,> in Perl space. SV* PL_ofs_sv =for hackers Found in file thrdvar.h =item PL_rs The input record separator - C<$/> in Perl space. SV* PL_rs =for hackers Found in file thrdvar.h =back =head1 AUTHORS The autodocumentation system was originally added to the Perl core by Benjamin Stuhl. Documentation is by whoever was kind enough to document their functions. =head1 SEE ALSO perlguts(1), perlapi(1)
