error, missing terminating character

Question

I have this missing terminating character, but I'm not sure what it wants or needs. I believe it's inside its inside the while second while loop. what can be done to fix this. I'm trying to input a text file with a string of paths. And then from there I parse through this string and put it to a link list. and then create a search function afterwards.

text file: path.txt

a/a1.txt
a/a2.txt
a/b/b3.txt
a/b/b4.txt
a/c/c4.txt
a/c/c5.txt
a/c/d/d6.txt
a/c/d/g
a/c/d/h
a/c/e/i/i7.txt
a/c/f/j/k/k8.txt

code:

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

typedef struct sMyPath{
        char *element;
        struct sMyPath *next;
} tMyPath;


int main(void)
{
        FILE *pFile;
        pFile = fopen("path.txt", "r");
        char inputstr[1024];
        tMyPath *curr, *first = NULL, *last = NULL;

//get the text file, and put it into a string inputstr

        if (pFile != NULL)
        {
                while(!feof(pFile))
                {
                        fgets(inputstr, sizeof(inputstr), pFile);
                }
        fclose(pFile);
        }
        else
        {
                printf("Could not open the file.\n");
        }

//using tokens to get each piece of the string
//seperate directories and text files, put it into a link list

        char *token = strtok(inputstr, "\");
        while (token != NULL)
        {
        if(last == NULL){
                //creating node for directory
                first = last = malloc (sizeof (*first));

                                printf("Theses are the contents\n");
                                printf("%s", texxt);
                        }

                }

In the line

char *token = strtok(inputstr, "\");

you need to use "\\" to specify a single backslash character.

A single backslash is treated as the start of a multi-character escape sequence.
