NAME
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.

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
