## 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

## 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.
