[char*] How to bind a function accept a char* argument?

[huangweiwu]

The code below comes up with a compile error.
"Return (char *)": cannot convert argument 1 from "const char *" to "char *".

void test_func(char* c) {} NB_MODULE(my_ext, m) { m.def("test_func", test_func, "c"_a); }

It's not supported. The nanobind Python bindings will call your function with a const char * from an internal buffer that you are not allowed to write to.
