See function openstabs in lineinfo:

function OpenStabs:boolean;
var
  ofm : word;
begin
  OpenStabs:=false;
  assign(f,paramstr(0));

and for dwarf in lnfodwarf there is OpenDwarf:

function OpenDwarf() : Boolean;
var
  oldfilemode : Word;
begin
  OpenDwarf := false;
  { open input file }
  assign(infile, paramstr(0));
  {$I-}
