NAME

       Dpkg::Arch - handle architectures


DESCRIPTION

       The Dpkg::Arch module provides functions to handle Debian
       architectures, wildcards, and mapping from and to GNU triplets.


FUNCTIONS

       $arch = get_raw_build_arch()
           Get the raw build Debian architecture, without taking into account
           variables from the environment.

       $arch = get_build_arch()
           Get the build Debian architecture, using DEB_BUILD_ARCH from the
           environment if available.

       $arch = get_raw_host_arch()
           Get the raw host Debian architecture, without taking into account
           variables from the environment.

       $arch = get_host_arch()
           Get the host Debian architecture, using DEB_HOST_ARCH from the
           environment if available.

       @arch_list = get_valid_arches()
           Get an array with all currently known Debian architectures.

       $multiarch = gnutriplet_to_multiarch($gnutriplet)
           Map a GNU triplet into a Debian multiarch triplet.

       $multiarch = debarch_to_multiarch($arch)
           Map a Debian architecture into a Debian multiarch triplet.

       $gnutriplet = debarch_to_gnutriplet($arch)
           Map a Debian architecture into a GNU triplet.

       $arch = gnutriplet_to_debarch($gnutriplet)
           Map a GNU triplet into a Debian architecture.

       $bool = debarch_eq($arch_a, $arch_b)
           Evaluate the equality of a Debian architecture, by comparing with
           another Debian architecture. No wildcard matching is performed.

       $bool = debarch_is($arch, $arch_wildcard)
           Evaluate the identity of a Debian architecture, by matchings with
           an architecture wildcard.

       $bool = debarch_is_wildcard($arch)
           Evaluate whether a Debian architecture is an architecture wildcard.

       $bool = debarch_is_concerned($arch, @arches)
           Evaluate whether a Debian architecture applies to the list of
           architecture restrictions, as usually found in dependencies inside
           square brackets.
