The line fullpath = temp; doesn't actually reset the var. I am not sure what I have to do. I have tried fullpath = *temp;. Could someone tell me why this is not working?

#include "stdio.h"
#include "stdlib.h" //Used for getenv();
#include "string.h" //Used for strcat();

int main(int argc, char* argv[])
{
    //Make vars
    FILE *self;
    FILE *ext;
    int lengthof;
    int sum;
    int fatpos;
    int i;
    int fcount;
    char filename[32];
    char *filedata;
    char *temp;
    char *fullpath;
    const int F_SIZE = 6144; //Size of this program (the stub)

    //Open self, set pointer to the end of the stub
    self = fopen(argv[0], "rb");
   	fseek(self, F_SIZE, SEEK_SET);

	//Read integer for number of files in archive
    fread(&fcount, sizeof(int), 1, self);
    
    //Figure out how long the FAT is
    sum = ((32 + sizeof(int)) * fcount) + sizeof(int);
    
    //Set up the position saver thing (used to keep the position in the FAT so program can seek back after file is read)
    fatpos = F_SIZE + sizeof(int);
    
    //Get the location of the temporary directory
    temp = getenv("TEMP");
    if(strlen(temp) > 3)
    {
         strcat(temp, "\\");
    }

	//Loop through the file names
	for(i = 0; i < fcount; i++)
	{
          fread(filename, 32, 1, self);                //Read the file name of 32 bytes max (will auto terminate at zero byte)
          fatpos += 32;                                //Add 32 to the position
          fread(&lengthof, sizeof(int), 1, self);      //Get length of file
          fatpos += sizeof(int);                       //Add a long to the position
          fseek(self, F_SIZE + sum, SEEK_SET);         //Go to the file
          sum += lengthof;                             //Add to the length …
