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




=head1 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)) { ... }




=head1 Description

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





=head1 API

C<Apache2::MPM> provides the following functions and/or methods:





=head2 C<query>

Query various attributes of the MPM

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

=over 4

=item obj: C<$class>
( C<L<Apache2::MPM class|docs::2.0::api::Apache2::MPM>> )

the class name

=item arg1: C<$const> ( C<L<Apache2::Const :mpmq group
constant|docs::2.0::api::Apache2::Const/C__mpmq_>> )

The MPM attribute to query.

=item ret: C<$query> ( boolean )

the result of the query

=item since: 2.0.00

=back

For example to test whether the mpm is static:

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







=head2 C<is_threaded>

Check whether the running Apache MPM is threaded.

  my $is_threaded = Apache2::MPM->is_threaded;

=over 4

=item obj: C<$class>
( C<L<Apache2::MPM class|docs::2.0::api::Apache2::MPM>> )

the class name

=item ret: C<$is_threaded> ( boolean )

threaded or not

=item since: 2.0.00

=back

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);






=head2 C<show>

What mpm is used

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

=over 4

=item obj: C<$class>
( C<L<Apache2::MPM class|docs::2.0::api::Apache2::MPM>> )

the class name

=item ret: C<$mpm> ( string )

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

=item since: 2.0.00

=back
