Exposing sendfile() for OS X

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? The answer is: you probably wouldn't. Sys::Sendfile is more portable, and supports more platforms.

Use 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.
