manipulating double arrays sent to function

in the parse function:

char **spliced;
return_val = splice(string,thespliced);

int splice(char *string, char *thespliced[])
{


        int i_string=0;
        int i_word_num=0;
        int i_word=0;
        int i=0;


        for( ; i_string < (strlen(string) - 1) ; ++i_string)
        {


                if(string[i_string] == ' ')
                {
                        ++i_word_num;
                        i_word = 0;
                        continue;
                }
                thespliced[i_word_num][i_word] = string[i_string];
                ++i_word;
        }

        return i_word;
}
