macOS odd warning

[farmerdoug]

int i, *tension;
tension = (int *) calloc(MAX_READINGS, sizeof(int));
if (fscanf(readings,"%s %d\n", reading_times[0], tension[0]) == EOF)

You didn't tell us what warning you're getting and we don't know anything about your reading_times[] variable.

fscanf() requires pointer-to-int for %d. What type is tension[0]?

thanks guys.
I found the error while writing the post but couldn't find out how to delete it. I left out the & in front of tension[0].

You probably do not want to test against EOF in *scanf functions, they return EOF only under very special circumstances. If you test against != 2, you will catch read errors and all other cases.
