NAME

IO::SocketAlarm::Util

EXPORTS

socketalarm

$alarm= socketalarm($socket);
$alarm= socketalarm($socket, @actions);
$alarm= socketalarm($socket, $event_mask, @actions);

This is a shortcut for IO::SocketAlarm->new:

$alarm= IO::SocketAlarm->new(
  socket => $socket,
  events => $event_mask,
  actions => \@actions,
);

is_socket

$bool= is_socket($thing);

Returns true if and only if the parameter is a socket at the operating system level. (for instance, the socket must not have been closed, which would release that file descriptor) It permits file handles or file descriptor numbers.

get_fd_table_str

$str= get_fd_table();        // scans fd 0..1023
$str= get_fd_table($max_fd); // specify your own upper limit

Return a human-readable string describing each open file descriptor. This is just for debugging, and relies on /proc/self/fd/ symlinks for anything other than sockets. For sockets, it prints the bound name and peer name of the socket.

Event Constants

EVENT_SHUT
EVENT_EOF
EVENT_IN
