Description

A representation of a C function

Examples

‘strcpy’

@libc = Fiddle.dlopen "/lib/libc.so.6"
   #=> #<Fiddle::Handle:0x00000001d7a8d8>
f = Fiddle::Function.new(
  @libc['strcpy'],
  [Fiddle::TYPE_VOIDP, Fiddle::TYPE_VOIDP],
  Fiddle::TYPE_VOIDP)
   #=> #<Fiddle::Function:0x00000001d8ee00>
buff = "000"
   #=> "000"
str = f.call(buff, "123")
   #=> #<Fiddle::Pointer:0x00000001d0c380 ptr=0x000000018a21b8 size=0 free=0x00000000000000>
str.to_s
=> "123"

ABI check

@libc = Fiddle.dlopen "/lib/libc.so.6"
   #=> #<Fiddle::Handle:0x00000001d7a8d8>
f = Fiddle::Function.new(@libc['strcpy'], [TYPE_VOIDP, TYPE_VOIDP], TYPE_VOIDP)
   #=> #<Fiddle::Function:0x00000001d8ee00>
f.abi == Fiddle::Function::DEFAULT
   #=> true

Socket::Option represents a socket option used by BasicSocket#getsockopt and BasicSocket#setsockopt. A socket option contains the socket family, protocol level, option name optname and option value data.

The InstructionSequence class represents a compiled sequence of instructions for the Ruby Virtual Machine.

With it, you can get a handle to the instructions that make up a method or a proc, compile strings of Ruby code down to VM instructions, and disassemble instruction sequences to strings for easy inspection. It is mostly useful if you want to learn how the Ruby VM works, but it also lets you control various settings for the Ruby iseq compiler.

You can find the source for the VM instructions in insns.def in the Ruby source.

The instruction sequence results will almost certainly change as Ruby changes, so example output in this documentation may be different from what you see.

Map from option/keyword string to object with completion.

Raises when ambiguously completable string is encountered.

Raises when switch is undefined.

Represents an XML Instruction; IE, <? … ?> TODO: Add parent arg (3rd arg) to constructor

BasicSpecification is an abstract class which implements some common code used by both Specification and StubSpecification.

Base exception class for RubyGems. All exception raised by RubyGems are a subclass of this one.

Raised by Gem::Resolver when a Gem::Dependency::Conflict reaches the toplevel. Indicates which dependencies were incompatible through conflict and conflicting_dependencies

Potentially raised when a specification is validated.

Used to raise parsing and loading errors
