] | How about something like this:
* Do a `fgets` and find out how long one line is
* Find the size of the file using `fseek` and `ftell`
```
fseek(fp, 0, SEEK_END);
size = ftell(fp);
```
* Divide by the size of the line
You can also use `fseeko` and `ftello` which work with `off_t`. | If it is safe to assume that all lines are of equal length, you can simply read in the first line, get its length, then get the file size, and divide file size by line length.
This will only work with fixed-width encodings (ASCII-7, the various 8-bit ANSI encodings, UTF-32); with variable-width encodings (e.g. UTF-8),... |
