translation.check\_str\_without\_nul
====================================

* **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 os.open().  Defaults to False because it is usually more
pain than benefit, but turned on by targetpypystandalone.
