Converts the contents of the database to an array of [key, value] arrays, and returns it.
Returns the bits in stat as a Integer
. Poking around in these bits is platform dependent.
fork { exit 0xab } #=> 26566 Process.wait #=> 26566 sprintf('%04x', $?.to_i) #=> "ab00"
Show pid and exit status as a string.
system("false") p $?.to_s #=> "pid 12766 exit 1"
Returns the least significant eight bits of the return code of stat. Only available if exited?
is true
.
fork { } #=> 26572 Process.wait #=> 26572 $?.exited? #=> true $?.exitstatus #=> 0 fork { exit 99 } #=> 26573 Process.wait #=> 26573 $?.exited? #=> true $?.exitstatus #=> 99
Returns the replacement string.
ec = Encoding::Converter.new("euc-jp", "us-ascii") p ec.replacement #=> "?" ec = Encoding::Converter.new("euc-jp", "utf-8") p ec.replacement #=> "\uFFFD"
Sets the replacement string.
ec = Encoding::Converter.new("utf-8", "us-ascii", :undef => :replace) ec.replacement = "<undef>" p ec.convert("a \u3042 b") #=> "a <undef> b"
Resets the digest to the initial state and returns self.
This method is overridden by each implementation subclass.
If none is given, returns the resulting hash value of the digest, keeping the digest’s state.
If a string is given, returns the hash value for the given string, resetting the digest to the initial state before and after the process.
Returns the resulting hash value and resets the digest to the initial state.
If none is given, returns the resulting hash value of the digest in a hex-encoded form, keeping the digest’s state.
If a string is given, returns the hash value for the given string in a hex-encoded form, resetting the digest to the initial state before and after the process.
Returns the resulting hash value in a hex-encoded form and resets the digest to the initial state.
Returns digest_obj.hexdigest().
If none is given, returns the resulting hash value of the digest in a base64 encoded form, keeping the digest’s state.
If a string
is given, returns the hash value for the given string
in a base64 encoded form, resetting the digest to the initial state before and after the process.
In either case, the return value is properly padded with ‘=’ and contains no line feeds.
Returns the resulting hash value and resets the digest to the initial state.
Creates a class to wrap the C struct described by signature
.
MyStruct = struct ['int i', 'char c']
Construct a new class given a C:
class klass
(CUnion
, CStruct
, or other that provide an entity_class)
types
(Fiddle::TYPE_INT, Fiddle::TYPE_SIZE_T, etc., see the C types constants)
corresponding members
Fiddle::Importer#struct
and Fiddle::Importer#union
wrap this functionality in an easy-to-use manner.
Example:
require 'fiddle/struct' require 'fiddle/cparser' include Fiddle::CParser types, members = parse_struct_signature(['int i','char c']) MyStruct = Fiddle::CStructBuilder.create(Fiddle::CUnion, types, members) obj = MyStruct.allocate

Similar to read, but raises EOFError
at end of string instead of returning nil
, as well as IO#sysread
does.

Reads size bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#read
for full details.
Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.
