Binary package “libio-fdpass-perl” in ubuntu oracular
module to pass a file descriptor over a socket
IO::FDPass, the small low-level module only has one purpose: pass a file
descriptor to another process, using a (streaming) unix domain socket (on
POSIX systems) or any (streaming) socket (on WIN32 systems). The ability to
pass file descriptors on windows is currently the unique selling point of
this module.
