APR::Const - Perl Interface for APR Constants

Synopsis

Top

  # make the constants available but don't import them
  use APR::Const -compile => qw(constant names ...);

  # w/o the => syntax sugar
  use APR::Const ("-compile", qw(constant names ...));

  # compile and import the constants
  use APR::Const qw(constant names ...);

Description

Top

This package contains constants specific to APR features.

Refer to the Apache2::Const description section (Description in docs::2.0::api::Apache2::Const) for more information.

Constants
