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
