Description
A representation of a C function
Examples
‘strcpy’
@libc = DL.dlopen "/lib/libc.so.6" => #<DL::Handle:0x00000001d7a8d8> f = Fiddle::Function.new(@libc['strcpy'], [TYPE_VOIDP, TYPE_VOIDP], TYPE_VOIDP) => #<Fiddle::Function:0x00000001d8ee00> buff = "000" => "000" str = f.call(buff, "123") => #<DL::CPtr:0x00000001d0c380 ptr=0x000000018a21b8 size=0 free=0x00000000000000> str.to_s => "123"
ABI check
@libc = DL.dlopen "/lib/libc.so.6" => #<DL::Handle:0x00000001d7a8d8> f = Fiddle::Function.new(@libc['strcpy'], [TYPE_VOIDP, TYPE_VOIDP], TYPE_VOIDP) => #<Fiddle::Function:0x00000001d8ee00> f.abi == Fiddle::Function::DEFAULT => true
