Go4Expert - Bubble sorting IP address

Am trying to a program that bubble sorts IP address. the IP address line has some string after which should remain in the same line after the bubble sort.

Code:

ypedef struct ipaddress



{



    short int w, x, y, z;



} ipaddress;



typedef struct logStruct



{



    ipaddress ip;



    char * as_line;



} log;



void getIP(ipaddress * ip, char * as_line)



{

    as_line+=3;



    ip->w = atoi(strtok(as_line, "."));



    ip->x = atoi(strtok(NULL, "."));





    ip->y = atoi(strtok(NULL, "."));





    ip->z = atoi(strtok(NULL, " "));



  

sortArray = calloc(sizeof(log *) , numLines);



    for (counter = 0; counter < numLines; counter++)

    {

        sortArray[counter] = calloc(sizeof(log),1);

        sortArray[counter]->as_line = calloc(sizeof(char),500);

        fgets(sortArray[counter]->as_line,500,myfile);

        strcpy(buffer,sortArray[counter]->as_line);

        getIP(&(sortArray[counter]->ip),buffer);

        /*sortArray[counter]->as_line*/

        }

                 

   bubbleSort(sortArray, numLines);



void bubbleSort(log * * array, int numLines)



{



log * temp_store;



        int i, j;



        

    for (i = 0; i < numLines; i++)



        for (j = 0; j < length-1; j++)



        {



            

    



              tempPointer = array[j];



                array[j] = array[j+1];



                array[j+1] = tempPointer;
