Apache2::MPM - Perl API for accessing Apache MPM information

Synopsis ^

  use Apache2::MPM ();
  # check whether Apache MPM is threaded
  if (Apache2::MPM->is_threaded) { do_something() }
  # which mpm is used
  my $mpm = lc Apache2::MPM->show;
  # query mpm properties
  use Apache2::Const -compile => qw(:mpmq);
  if (Apache2::MPM->query(Apache2::Const::MPMQ_STATIC)) { ... }

Description ^

Apache2::MPM provides the Perl API for accessing Apache MPM information.


Apache2::MPM provides the following functions and/or methods:


Query various attributes of the MPM

  my $query = Apache2::MPM->query($const);
obj: $class ( Apache2::MPM class )

the class name

arg1: $const ( Apache2::Const :mpmq group constant )

The MPM attribute to query.

ret: $query ( boolean )

the result of the query

since: 2.0.00

For example to test whether the mpm is static:

  use Apache2::Const -compile => qw(MPMQ_STATIC);
  if (Apache2::MPM->query(Apache2::Const::MPMQ_STATIC)) { ... }


Check whether the running Apache MPM is threaded.

  my $is_threaded = Apache2::MPM->is_threaded;
obj: $class ( Apache2::MPM class )

the class name

ret: $is_threaded ( boolean )

threaded or not

since: 2.0.00

Note that this functionality is just a shortcut for:

  use Apache2::Const -compile => qw(MPMQ_IS_THREADED);
  my $is_threaded = Apache2::MPM->query(Apache2::Const::MPMQ_IS_THREADED);


What mpm is used

  my $mpm = Apache2::MPM->show();
obj: $class ( Apache2::MPM class )

the class name

ret: $mpm ( string )

the name of the MPM. e.g., "Prefork".

since: 2.0.00
