An example:

//strtok-ing a string strtok gave you.
// You can do this with strtok_r, but not strtok, because
// strtok would lose its place.

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

int main() {
        char rstr[]="a:b:c|d:e:f|g:h:i";
        char *tmp1, *tok1;

        tok1=strtok_r(rstr, "|", &tmp1);
        while(tok1 != NULL)
                char *tmp2, *tok2;
                printf("Outer token:  '%s'\n", tok1);

                tok2=strtok_r(tok1, ":", &tmp2);
                while(tok2 != NULL)
                        printf("\tInner Token:  '%s'\n", tok2);
                        tok2=strtok_r(NULL, ":", &tmp2);

                tok1=strtok_r(NULL, "|", &tmp1);


$ gcc strtok_r.c
$ ./a.out

Outer token:  'a:b:c'
        Inner Token:  'a'
        Inner Token:  'b'
        Inner Token:  'c'
Outer token:  'd:e:f'
        Inner Token:  'd'
        Inner Token:  'e'
        Inner Token:  'f'
Outer token:  'g:h:i'
        Inner Token:  'g'
        Inner Token:  'h'
        Inner Token:  'i'
