I keep trying to use fscanf() and for some reason I can't get the syntax down and always get seg faults. I'm on a SunOS 5.5.1, and my current code looks like this:

int n1, n2, n3, n4, n5, n6;

/* open config file */
if (fileptr = fopen(filename,"r") == NULL) {
printf("couldn't open file, errno: %d\n", errno);
exit(0);
}

fscanf(fileptr, "%d %d %d %d %d %d", &n1, &n2, &n3, &n4, &n5, &n6);


(end)
######### FIRST LINE FILE LOOKS LIKE THIS #######
4500 4017 1 0 1 2

I've been trying to get past this for hours now and was hoping someone could offer some advice or explanation as to why it keeps seg faulting. THANKS!

The bug must be elsewhere. The code you posted looks good. I tried it on hp-ux and it worked.

Thanks for checking, I'll keep looking around...

Hi,
I found the answer for your problem
Take a look at the following program :

int n1, n2, n3, n4, n5, n6;

/* open config file */
if ((fileptr = fopen(filename,"r") )== NULL) {
printf("couldn't open file, errno: %d\n", errno);
exit(0);
}

fscanf(fileptr, "%d %d %d %d %d %d", &n1, &n2, &n3, &n4, &n5, &n6);


What I did was I introduced a pair of brackets around "fileptr".
I can bet that, you won't get the error any more.

thank you,
