• name: check_str_without_nul
  • description: Forbid NUL chars in strings in some external function calls
  • option type: boolean option
  • default: False

If turned on, the annotator will keep track of which strings can potentially contain NUL characters, and complain if one such string is passed to some external functions — e.g. if it is used as a filename in Defaults to False because it is usually more pain than benefit, but turned on by targetpypystandalone.
