NAME

perlintern - autogenerated documentation of purely internal                  Perl functions
 

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, they are not for use in extensions!
is_gv_magical
Returns "TRUE" if given the name of a magical GV.

Currently only useful internally when determining if a GV should be created even in rvalue contexts.

"flags" 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)


LVRET
True if this op will be the return value of an lvalue subroutine
PL_DBsingle
When Perl is run in debugging mode, with the -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 "PL_DBsub".

        SV *    PL_DBsingle


PL_DBsub
When Perl is run in debugging mode, with the -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 "PL_DBsingle".

        GV *    PL_DBsub


PL_DBtrace
Trace variable used when Perl is run in debugging mode, with the -d switch. This is the C variable which corresponds to Perl's $DB::trace variable. See "PL_DBsingle".

        SV *    PL_DBtrace


PL_dowarn
The C variable which corresponds to Perl's $^W warning variable.

        bool    PL_dowarn


PL_last_in_gv
The GV which was last used for a filehandle input operation. ("<FH>")

        GV*     PL_last_in_gv


PL_ofs_sv
The output field separator - $, in Perl space.

        SV*     PL_ofs_sv


PL_rs
The input record separator - $/ in Perl space.

        SV*     PL_rs
