   probably you can do it with strstr(), no? something like strstr(str + fromIndex, substr)

   int indexOf(string str, string substr, int fromIndex)
   
   int lastIndexOf(string str, string substr, int fromIndex)
   

   I'm describe error. return value type is int.

   /* Returns a pointer to the beginning of the located substring.
      Returns NULL if the substring is not found or 'fromIndex' is larger than the length of str */
   char *sc_str_indexof(const char *str, const char *needle, uint32_t fromIndex, int reverse);

   maybe we can do something like this, similar to strstr(), it may return located string position.
