There's a helper in the stdlib type for arrays of C strings: <https://nim-lang.org/docs/system.html#cstringArray> If you look in the system module there's other helpers for C string arrays like: <https://nim-lang.org/docs/system.html#cstringArrayToSeq%2CcstringArray> > but I cannot return it from the function. I can cast of course, but not sure > is it good way or not Yah, coming from a C background it tripped me up at first as well. `UncheckedArray[T]` represents the actual array in Nim not the array pointer. So you need `ptr UncheckedArray[T]` to emulate a C pointer array, e.g. an array of ints in C would become `ptr UncheckedArray[int]` in Nim. I kept thinking of it as an alias for `int *a` but it's not. So to get an `int**` you'd need: var x: ptr UncheckedArray[cstring] f(x.addr) ## this makes a `ptr ptr array[cstring]` basically Run
