Returns new ancillary data for IP_PKTINFO.
If spec_dst is not given, addr is used.
IP_PKTINFO is not standard.
Supported platform: GNU/Linux

Replace %w+% into the environment value of what is contained between the %‘s This method is used for REG_EXPAND_SZ.

Takes source
, which can be a string of Ruby
code, or an open File
object. that contains Ruby
source code. It parses and compiles using parse.y.
Optionally takes file
, path
, and line
which describe the file path, real path and first line number of the ruby code in source
which are metadata attached to the returned iseq
.
file
is used for ‘__FILE__` and exception backtrace. path
is used for require_relative
base. It is recommended these should be the same full path.
options
, which can be true
, false
or a Hash
, is used to modify the default behavior of the Ruby
iseq compiler.
For details regarding valid compile options see ::compile_option=
.

Sets the read timeout, in seconds, for self
to integer sec

Argument sec
must be a non-negative numeric value:
http = Net::HTTP.new(hostname) http.read_timeout # => 60 http.get('/todos/1') # => #<Net::HTTPOK 200 OK readbody=true> http.read_timeout = 0 http.get('/todos/1') # Raises Net::ReadTimeout.

Return the byte offset of the start of the line corresponding to the given byte offset.
The line number where this location starts.
The column number in bytes where this location starts from the start of the line.
