Apache2::MPM(3) Perl API for accessing Apache MPM information


  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)) { ... }


"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
