It's good to take a look in your compiler's help files first. Can't help you too much but I found a short example code which aims at explaining how it works and how to write another code with strtok.

/* STRTOK.C: In this program, a loop uses strtok
 * to print all the tokens (separated by commas
 * or blanks) in the string named "string".
 */

#include <string.h>
#include <stdio.h>

char string[] = "A string\tof ,,tokens\nand some  more tokens";
char seps[]   = " ,\t\n";
char *token;

void main( void )
{
   printf( "%s\n\nTokens:\n", string );
   /* Establish string and get the first token: */
   token = strtok( string, seps );
   while( token != NULL )
   {
      /* While there are tokens in "string" */
      printf( " %s\n", token );
      /* Get next token: */
      token = strtok( NULL, seps );
   }
}

hope it helps

Sorry, it's just a microsoft example

Here is a little bit of code, but not much..

Ok, take this sentence:
Pearl Jam - Alive.mp3
If you want the artist and song name, you would use "-" as the token here, not a space.

int main () {
    char blah[] = "Pearl Jam - Alive.mp3";
    char *artist, *song;

    /* Ok, we want everything from the start of "blah" UNTILL the "-" */
    artist = strtok(blah, "-");

    /* Now we want everything from the current space (NULL) to the end of the line ("") */
    song = strtok(NULL, "");

    printf("Artist: %s - Song: %s", artist, song);
    return(0);
}

So basically, strtok(StartPosition, "EndPosition"); means you return everything from StartPosition to "EndPosition".

Hope this helps a little
