    The BeginReading function returns a const pointer to the first element of the string's internal buffer.

     const char_type* BeginReading() const;


    The resulting character array is not necessarily null-terminated. The length of the array is determined by the result of the Length method.

    Example Code

      // count the number of times a particular character appears in the string
      PRUint32 CountChar(const nsACString& str, char c)
        const char* start = str.BeginReading();
        const char* end = str.EndReading();
        PRUint32 count = 0;
        while (start != end)
          if (*start++ == c)
        return count;
