# NAME

Sys::Sendfile::OSX - Exposing sendfile() for OS X

# SYNOPSIS

    use Sys::Sendfile::OSX qw(sendfile);

    open my $local_fh, '<', 'somefile';

    my $socket_fh = IO::Socket::INET->new(

      PeerHost => "10.0.0.1",

      PeerPort => "8080"

    );

    my $rv = sendfile($local_fh, $socket_fh);

# DESCRIPTION

The sendfile() function is a zero-copy function for transferring the

contents of a filehandle to a streaming socket.

As per the man pages, the sendfile() function was made available as of Mac

OS X 10.5.

# Sys::Sendfile

Why would you use this module over [Sys::Sendfile](https://metacpan.org/pod/Sys::Sendfile)? The answer is: you

probably wouldn't. [Sys::Sendfile](https://metacpan.org/pod/Sys::Sendfile) is more portable, and supports more

platforms.

Use [Sys::Sendfile](https://metacpan.org/pod/Sys::Sendfile).

# EXPORTED FUNCTIONS

- sendfile($from, $to\[, $count\]\[, $offset\])

    Pipes the contents of the filehandle `$from` into the socket stream `$to`.

    Optionally, only `$count` bytes will be sent across to the socket. Specifying a

    `$count` of 0 is the same as sending the entire file, as per the man page.

    Also optionally, `$offset` can be specified to set a specific-sized chunk from

    a specific offset.
