function splitDisassembledString(DisassembledString)

Slipts a disassembler string, returning 4 strings. The address, bytes, opcode and extra field. To be used with return from disassemble.

Function Parameters

Parameter Type Description
DisassembledString string The disassembled string to split


Examples

 local addr = getAddress('00123ABC')
 local disassStr = disassemble(addr)
 local extraField, opcode, bytes, address = splitDisassembledString(disassStr)
 local addr_2 = addr + getInstructionSize(addr)
 local disassStr_2 = disassemble(addr)
 local extraField_2, opcode_2, bytes_2, address_2 = splitDisassembledString(disassStr)


Code: 

 local addr = getAddress('Tutorial-x86_64.exe+164A7')
 local disassStr = disassemble(addr)
 local extraField, opcode, bytes, address = splitDisassembledString(disassStr)
 for i = 1, 10 do
   local a = getNameFromAddress(address) or address
   local b = bytes .. string.rep(' ', 20 - #bytes)
   local o = opcode .. string.rep(' ', 30 - #opcode)
   print(string.format('%s:  %s  -  %s    %s', a, b, o, extraField))
   addr = addr + getInstructionSize(addr)
   disassStr = disassemble(addr)
   extraField, opcode, bytes, address = splitDisassembledString(disassStr)
 end
