       "ModPerl::Util" provides modperl utilities API.

AAPPII
       "ModPerl::Util" provides the following functions and/or methods:

       ""ccuurrrreennttccaallllbbaacckk""

       Returns the currently running callback name, e.g.
       'PerlResponseHandler'.

         $callback = ModPerl::Util::currentcallback();

       ret: $callback ( string )
       since: 2.0.00

       ""ccuurrrreennttppeerrlliidd""

       Return the memory address of the perl interpreter

         $perlid = ModPerl::Util::currentperlid();

       ret: $perlid ( string )
           Under threaded perl returns something like: 0x92ac760

           Under non-thread perl returns 0x0

       since: 2.0.00

       Mainly useful for debugging applications running under threaded-perl.

       ""eexxiitt""

       Terminate the request, but not the current process (or not the current
       Perl interpreter with threaded mpms).

         ModPerl::Util::exit($status);

       opt arg1: $status ( integer )
           The exit status, which as of this writing is ignored. (it's
           accepted to be compatible with the core "exit" function.)

       ret: no return value
       since: 2.0.00

       Normally you will use the plain "exit()" in your code. You don't need
       to use "ModPerl::Util::exit" explicitly, since modperl overrides
       "exit()" by setting "CORE::GLOBAL::exit" to "ModPerl::Util::exit". Only
       if you redefine "CORE::GLOBAL::exit" once modperl is running, you may
       want to use this function.

       The original "exit()" is still available via "CORE::exit()".

       "ModPerl::Util::exit" is implemented as a special "die()" call,
       therefore if you call it inside "eval BLOCK" or "eval "STRING"", while
       an exception is being thrown, it is caught by "eval". For example:

         exit;
         print "Still running";

       will not print anything. But:

         eval {
            exit;
         }
         print "Still running";

       will print Still running. So you either need to check whether the
       exception is specific to "exit" and call "exit()" again:

         use ModPerl::Const -compile => 'EXIT';
         eval {
            exit;
         }
         exit if $@ && ref $@ eq 'APR::Error' && $@ == ModPerl::EXIT;
         print "Still running";

       or use "CORE::exit()":

         eval {
            CORE::exit;
         }
         print "Still running";

       and nothing will be printed. The problem with the latter is the current
       process (or a Perl Interpreter) will be killed; something that you
       really want to avoid under modperl.

       ""uunnllooaaddppaacckkaaggee""

       Unloads a stash from the current Perl interpreter in the safest way
       possible.

         ModPerl::Util::unloadpackage($stash);

       arg1: $stash ( string )
           The Perl stash to unload. e.g. "MyApache2::MyData".

       ret: no return value
       since: 2.0.00

       Unloading a Perl stash (package) is a complicated business. This
       function tries very hard to do the right thing. After calling this
       function, it should be safe to "use()" a new version of the module that
       loads the wiped package.

       References to stash elements (functions, variables, etc.) taken from
       outside the unloaded package will still be valid.

       This function may wipe off things loaded by other modules, if the
       latter have inserted things into the $stash it was told to unload.

       If a stash had a corresponding XS shared object (.so) loaded it will be
       unloaded as well.

       If the stash had a corresponding entry in %INC, it will be removed from
       there.

       "unloadpackage()" takes care to leave sub-stashes intact while
       deleting the requested stash. So for example if "CGI" and "CGI::Carp"
       are loaded, calling "unloadpackage('CGI')" won't affect "CGI::Carp".

       ""uunnttaaiinntt""

       Untaint the variable, by turning its tainted SV flag off (used
       internally).

         ModPerl::Util::untaint($taintedvar);

       arg1: $taintedvar (scalar)
       ret: no return value
           $taintedvar is untainted.

       since: 2.0.00

       Do not use this function unless you know what you are doing. To learn
       how to properly untaint variables refer to the perlsec manpage.
