Scan scalars for built in types
Thrown when PTY::check
is called for a pid that represents a process that has exited.
Socket::AncillaryData
represents the ancillary data (control information) used by sendmsg and recvmsg system call. It contains socket family
, control message (cmsg) level
, cmsg type
and cmsg data

Zlib::GzipWriter
is a class for writing gzipped files. GzipWriter
should be used with an instance of IO
, or IO-like, object.
Following two example generate the same result.
Zlib::GzipWriter.open('hoge.gz') do |gz| gz.write 'jugemu jugemu gokou no surikire...' end File.open('hoge.gz', 'w') do |f| gz = Zlib::GzipWriter.new(f) gz.write 'jugemu jugemu gokou no surikire...' gz.close end
To make like gzip(1) does, run following:
orig = 'hoge.txt' Zlib::GzipWriter.open('hoge.gz') do |gz| gz.mtime = File.mtime(orig) gz.orig_name = orig gz.write IO.binread(orig) end
NOTE: Due to the limitation of Ruby’s finalizer, you must explicitly close GzipWriter
objects by Zlib::GzipWriter#close
etc. Otherwise, GzipWriter
will be not able to write the gzip footer and will generate a broken gzip file.

Note: Don’t use this class directly. This is an internal class.
Error raised when an error occurs on the underlying communication protocol.
Class
responsible for converting between an object and its id.
This, the default implementation, uses an object’s local ObjectSpace
__id__ as its id. This means that an object’s identification over drb remains valid only while that object instance remains alive within the server runtime.
For alternative mechanisms, see DRb::TimerIdConv
in drb/timeridconv.rb and DRbNameIdConv in sample/name.rb in the full drb distribution.
An Array
wrapper that can be sent to another server via DRb
.
All entries in the array will be dumped or be references that point to the local server.
Class
handling the connection between a DRbObject
and the server the real object lives on.
This class maintains a pool of connections, to reduce the overhead of starting and closing down connections for each method call.
This class is used internally by DRbObject
. The user does not normally need to deal with it directly.

Gateway id conversion forms a gateway between different DRb
protocols or networks.
The gateway needs to install this id conversion and create servers for each of the protocols or networks it will be a gateway between. It then needs to create a server that attaches to each of these networks. For example:
require 'drb/drb' require 'drb/unix' require 'drb/gw' DRb.install_id_conv DRb::GWIdConv.new gw = DRb::GW.new s1 = DRb::DRbServer.new 'drbunix:/path/to/gateway', gw s2 = DRb::DRbServer.new 'druby://example:10000', gw s1.thread.join s2.thread.join
Each client must register services with the gateway, for example:
DRb.start_service 'drbunix:', nil # an anonymous server gw = DRbObject.new nil, 'drbunix:/path/to/gateway' gw[:unix] = some_service DRb.thread.join
