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.

API

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

query

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)) { ... }

is_threaded

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);

show

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
