# 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
