I have no idea what you're even trying to do with string1 = tmp1;. That operation does not make sense.

Every time you call strtok_r(string1, ...) you are telling it to start over! Remember how strtok works.

Code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
/* *From http://www.gsp.com/cgi-bin/man.cgi?section=3&topic=strtok_r
 A FreeBSD man pages  * */

int main()
{
    char string1[80]="This;is.a:test:of=the/string\\tokenizer-function."; // You can assign directly, without strcpy
    const char *sep = "\\/:;=-";               /*Delimiters*/
    char *word, *tmp1;                   /*For the loop, *word is the return value, tmp1 is the temporary holder of the rest*/

    word=strtok_r(string1, sep, &tmp1);

    while(word != NULL)
    {
        printf("word = '%s'\n", word);
        word=strtok_r(NULL, sep, &tmp1);
    }

    return 0;
}

Code:
$ gcc strtok.c
$ ./a.out

word = 'This'
word = 'is.a'
word = 'test'
word = 'of'
word = 'the'
word = 'string'
word = 'tokenizer'
word = 'function.'
