python - PyErr_SetString's string argument: is it borrowed? -

-

How does PyErr_SetString handle passage in C-string? Like it is safe to do: 

  {int age = 12; Std :: stringstream ostr; Ostr & lt; & Lt; "I am" & lt; & Lt; Age & lt; & Lt; "Year is old and what is this?"; PyErr_SetString (PyExc_RuntimeError, ostr.str (..c_str ()); }

Obviously this is 'converted to a string object', but is it necessary that the content will be copied?

It is safe to do so, copying the contents of the wire before returning the Python. It applies only to other Python string operations.

In general, only reference to python objects (poobect *) can be borrowed or stolen, and unless interpreted otherwise, the interpreter copies the arguments.

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
