Returns the least significant eight bits of the return code of the process if it has exited; nil otherwise:
`exit 99` $?.exitstatus # => 99
Obtains a lock, runs the block, and releases the lock when the block completes. See the example under Thread::Mutex.
Wakes up all threads waiting for this lock.
Returns a printable version of ec
ec = Encoding::Converter.new("iso-8859-1", "utf-8") puts ec.inspect #=> #<Encoding::Converter: ISO-8859-1 to UTF-8>
Returns a new String containing informations about the map:
m = ObjectSpace::WeakKeyMap.new m[key] = value m.inspect # => "#<ObjectSpace::WeakKeyMap:0x00000001028dcba8 size=1>"
Creates a printable version of the digest object.
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.
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']
Creates a class to wrap the C union described by signature.
MyUnion = union ['int i', 'char c']
Decodes a BER- or DER-encoded value and creates an ASN1Data instance. der may be a String or any object that features a .to_der method transforming it into a BER-/DER-encoded String+
der = File.binread('asn1data') asn1 = OpenSSL::ASN1.decode(der)
Return true if the PRNG has been seeded with enough data, false otherwise.

Generate a Table Caption element as a string.
align can be a string, giving the alignment of the caption (one of top, bottom, left, or right). It can be a hash of all the attributes of the element. Or it can be omitted.
The body of the element is provided by the passed-in no-argument block.
caption("left") { "Capital Cities" } # => <CAPTION ALIGN=\"left\">Capital Cities</CAPTION>
Adds a separated list. The list is separated by comma with breakable space, by default.
seplist iterates the list using iter_method. It yields each object to the block given for seplist. The procedure separator_proc is called between each yields.
If the iteration is zero times, separator_proc is not called at all.
If separator_proc is nil or not given, +lambda { comma_breakable }+ is used. If iter_method is not given, :each is used.
For example, following 3 code fragments has similar effect.
q.seplist([1,2,3]) {|v| xxx v } q.seplist([1,2,3], lambda { q.comma_breakable }, :each) {|v| xxx v } xxx 1 q.comma_breakable xxx 2 q.comma_breakable xxx 3
