Return a char array with any length in C?

Question

How do I return a char array with any length in C?

char string[](int, int);

doesn't work; is there a way to return a char array?

Answer 1

You are unable to do that in C. Instead, return a pointer.

char *string(int length, int unused) {
  char *s = calloc(x, sizeof(char));
  return s;
}
