why does fgets() return 1 on empty lines

[Jochen Daum]

Hi,

I'm writing a small configuration file parser.  A small problem is that on all empty lines fgets returns string "1". My lines end with \n (unix style). Is this intentional?

your line breaks take up 1 byte and that's what fget's returns:

Hi,

It says:

Returns a string of up to length - 1 bytes read from the file pointed to by handle .

If an error occurs, returns FALSE.

How would I distinguish a line with "\n" and "1\n" then?

I'm confused, I can't find any mention of the length of the line being returned.

sorry, my answer was totally confused
