PERLINTERN !!!PERLINTERN NAME DESCRIPTION AUTHORS SEE ALSO ---- !!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. () 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. !!SEE ALSO perlguts(1), perlapi(1) ----
