perlintern − autogenerated documentation of purely internal |
Perl functions |
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
The autodocumentation system was originally added to the Perl core by Benjamin Stuhl. Documentation is by whoever was kind enough to document their functions.
