How to use getSymbolFromAddress()

I tried this and it did not print anything:

Code:
  local address = getMemoryViewForm().DisassemblerView.SelectedAddress
  print(getMainSymbolList().getSymbolFromAddress(address))


I want to get the symbol name of the function/address so I can extract the offset

you're best of using getNameFromAddress and parse the +xxx part

but if you really want to, it's something like this:

Code:

local address = getMemoryViewForm().DisassemblerView.SelectedAddress
local symbolinfo=getMainSymbolList().getSymbolFromAddress(address)

if symbolinfo then
  printf("symbol address of %s=%x, so offset is %x", symbolinfo.searchkey, symbolinfo.address, address-symbolinfo.address )
else
  printf("not a symbol. Checking modules")
  local ml=enumModules()
  for i=1,#ml do
    if address>=ml[i].Address then
      local ms=getModuleSize(ml[i].Name)  --7.6 will have .Size part of the modulelist
      if address<ml[i].Address+ms then
        printf("module address=%x, so offset is %x", ml[i].Address, address-ml[i].Address)
      end
      break --the modulelist is sorted by address, so if this isn't it, it's not in the list
    end
  end
end
