Is there a way to store data into different structures depending on the file being read?

I'm attempting to write a program that will (in part) read data from three different .txt files into three different structures, so they can be used to determine the states of various appliances. Initially I wrote a version of the code that used a single file and it worked fine, the problem is trying to add options to the code.

I have the code to read the file:

void ReadDataFile(char *location) {
int t=0, k;
char src[100]={};

strcat( strcat(src, MYPATH), location);

ptr = fopen(src,"r");

if(ptr == NULL)
{
    printf("Error!\n");
    exit(1);
}
printf("Success!\n");

From here I'm trying to use if statements to determine where data is stored. An example of the first one is:

if(location == "living_room.txt") {

    printf("Filepath found!\n");

while ((!feof(ptr)) && (t<24)) {
    //read time
    fscanf(ptr, "%s", &(*ptr2)[t].LR.hour);
    //read temperatures
    fscanf(ptr, "%f%f", &(*ptr2)[t].LR.eTemp, &(*ptr2)[t].LR.iTemp);
    //read humidity
    fscanf(ptr, "%f",  &(*ptr2)[t].LR.hum);
    //read motion data
    for ( k=0; k<6; k++)
        fscanf(ptr,"%f",  &(*ptr2)[t].LR.mot[k]);

    t++;

} }

I can't figure out what should be in the arguments for the if statement (if this is a sensible approach).

Thanks in advance.
