NAME

Linux::Perl - Linux system calls with pure Perl

SYNOPSIS

    my $efd = Linux::Perl::eventfd->new();

    #...or, if you know your architecture:
    my $efd = Linux::Perl::eventfd::x86_64->new();

DESCRIPTION

In memory-sensitive environments it is useful to minimize the number of XS modules that Perl loads. Oftentimes the CPAN modules that implement support for various Linux system calls, though, will bring in XS for the sake of writing platform-neutral code.

Linux::Perl accommodates use cases where platform neutrality is less of a concern than minimizing memory usage.

MODULES

Each family of system calls lives in its own namespace under Linux::Perl:

The distribution contains a number of other modules, none of which is currently intended for outside use.

PLATFORM-SPECIFIC INVOCATION

Each Linux::Perl system call implementation can be called with a platform-neutral syntax as well as with a platform-specific one; for example:

    my $efd = Linux::Perl::eventfd->new();

    my $efd = Linux::Perl::eventfd::x86_64->new();

The platform-specific call is a bit lighter because it avoids loading Config to determine the current platform.

PLATFORM SUPPORT

x86_64 and arm are the best-supported platforms. i686 and i386 also have some support.

Support for adding new platforms just involves adding new modules with the necessary constants to the distribution.

Note also that a 64-bit Perl is generally assumed.
