Read PPM file header in C

Vote count:

I am currently trying to read a PPM file header and collect the data. I get a seg fault error though. Here is what I have:

int                 ROWS,COLS,BYTES;
char                header[80];
FILE                *fpt;

fpt = fopen("retna.ppm", "r");
fscanf(fpt,"%s %d %d %d", header, &ROWS, &COLS, &BYTES);

I am currently trying to grab P6 for header, Rows columns and the max pixel. Any thoughts?
