[FIXED] Why is my program perceiving an EOF condition way before my file actually ends?

Issue

My code reads line by line from a text file and stores the lines in a massive array of char pointers. When I use an ordinary text file, this works with no issues. However, when I try to read from the 'dictionary.txt' file I'm supposed to be using, my program detects EOF after reading the first of MANY lines in the file.

int i = 0;
while( 1 ) {
    
    size_t size = 50;
    fseek( dicFile, 0L, getline( &dictionary[i++], &size, dicFile) ); 
    printf( "%d:\t%s", i, dictionary[i - 1] );
    
    if( feof( dicFile ) ) {  
            fclose( dicFile );
            break;  
    }
    
}
puts("finished loading dictionary");

Here is the start of the dictionary file I'm attempting to load:

A
A's
AA's
AB's
ABM's
AC's
ACTH's
AI's
AIDS's
AM's
AOL
AOL's
ASCII's
ASL's
ATM's
ATP's
AWOL's
AZ's

The output is get from this portion of the program is:

1:  A
2:  finished loading dictionary

Thanks for any help.

Solution

Your third argument to fseek() is nuts. I've seen at least one implementation that treated every out of range third argument as SEEK_END. Oops.

You should just call getline() in the loop instead. In fact, just check the return value of getline() for -1 and get rid of that feof().
