Thread: Passing pointers to arrays of char arrays

I have an array containing arrays of chars, these are tokens from a tokenised string!!! so basically, looks something like....

- string one -
- string two -
- string three -

and so on....

Basically, I want to access this array of tokens in another function in my program!

Code:

char ** stringTokenizer(char * theData, char * theDelims){
  static char *Token[5];   /* ARRAY TO STORE POINTERS TO TOKENS */
  /* FUNCTION TOKENISES INPUT STRING HERE AND RETURNS THE TOKENS */
  return tokens;
}
  
main () {
  char ** tokens;  /* POINTER TO THE TOKENS */
  char mystring = "This is a test string";
  
  /* TOKENISE mystring DATA */
  tokens = stringTokenizer(mystring, " \r \n : ; #");
  
  /*
    T0 ACCESS THE TOKENS:
       tokens[0] = "This"
       tokens[1] = "is"
        tokens[2] = "a"
        tokens[3] = "test"
        tokens[4] = "string"
  */
  if (strcasecmp(tokens[0], "this") == 0) {  /* COMPARE FIRST TOKEN */
    printf("found \"this\" token\n");
  }
  
  anotherFunction(tokens);   /* CALL ANOTHER FUNCTION AND PASS THE TOKENS ARRAY TO IT! */
}  

anotherFunction(inToks) {

}

I know this is not the best description! ...But, it shows the fundamental concept of what goes on! ...I have a pointer to an array of pointers that point to individual char arrays (the tokens), I want to pass this pointer to the calling funciton so i can use the tokens in the other funciton!!!!!!

I hope this makes some sense!!!!!!

I want to be able to access the tokens (in the other function) by doing something similar to ;

tokens[x] (will retrieve the token in position x)

...In the same way as i can in the main function!!!! ...Basically, I want to compare the tokens and find out what tokens contain certain data!!! (it is for university coursework, for a client server application, so packet data is the individual tokens and needs to be processed in different functions!!!!)



Thanx for any help!!!!!!!! I hope it is understandable what i am trying to do!!!!!!!!
