Unpacks sockaddr into port and ip_address.

sockaddr should be a string or an addrinfo for AF_INET/AF_INET6.

sockaddr = Socket.sockaddr_in(80, "127.0.0.1")
p sockaddr #=> "\x02\x00\x00P\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00"
p Socket.unpack_sockaddr_in(sockaddr) #=> [80, "127.0.0.1"]

Packs path as an AF_UNIX sockaddr string.

Socket.sockaddr_un("/tmp/sock") #=> "\x01\x00/tmp/sock\x00\x00..."

Returns true iff the scan pointer is at the beginning of the line.

s = StringScanner.new("test\ntest\n")
s.bol?           # => true
s.scan(/te/)
s.bol?           # => false
s.scan(/st\n/)
s.bol?           # => true
s.terminate
s.bol?           # => true

Returns reference counter of Dispatch interface of WIN32OLE object. You should not use this method because this method exists only for debugging WIN32OLE.

Returns the array of WIN32OLE_METHOD object . The element of the array is property (settable) of WIN32OLE object.

excel = WIN32OLE.new('Excel.Application')
properties = excel.ole_func_methods

Initialize WIN32OLE object(ActiveX Control) by calling IPersistMemory::InitNew.

Before calling OLE method, some kind of the ActiveX controls created with MFC should be initialized by calling IPersistXXX::InitNew.

If and only if you received the exception “HRESULT error code: 0x8000ffff catastrophic failure”, try this method before invoking any ole_method.

obj = WIN32OLE.new("ProgID_or_GUID_of_ActiveX_Control")
obj.ole_activex_initialize
obj.method(...)

Invoked as a callback whenever a singleton method is undefined in the receiver.

module Chatty
  def Chatty.singleton_method_undefined(id)
    puts "Undefining #{id.id2name}"
  end
  def Chatty.one()   end
  class << self
     undef_method(:one)
  end
end

produces:

Undefining one

This method injects an instance variable unconverted_fields into row and an accessor method for row called unconverted_fields(). The variable is set to the contents of fields.

Convenience method for Shell::CommandProcessor.undef_system_command

Establishes proc on thr as the handler for tracing, or disables tracing if the parameter is nil.

See Kernel#set_trace_func.

Adds proc as a handler for tracing.

See Thread#set_trace_func and Kernel#set_trace_func.

Establishes proc as the handler for tracing, or disables tracing if the parameter is nil.

Note: this method is obsolete, please use TracePoint instead.

proc takes up to six parameters:

• an event name

• a filename

• a line number

• an object id

• a binding

• the name of a class

proc is invoked whenever an event occurs.

Events are:

c-call

call a C-language routine

c-return

return from a C-language routine

call

call a Ruby method

class

start a class or module definition

end

finish a class or module definition

line

execute code on a new line

raise

raise an exception

return

return from a Ruby method

Tracing is disabled within the context of proc.

  def test
    a = 1

  }
