The only thing that I'm not sure about is whether 1000 bytes are guaranteed to be enough. Some quick Googling tells me that path lengths of 4096 are possible. Maybe we could allocate a temporary large array on the heap if the readlink call fails with the 1000 byte buffer on the stack?</p></pre>

And though st.st_size is mentioned in readlink man page, it may not return useful value.</p>

But of course I could have a missed a bug report about someone with a huge symlink target.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Checking what Qt does... ah, PATH_MAX if defined, otherwise a loop which reallocs twice more every time (starting from 256 bytes).
Personally I'm tempted to just make it 4096, "it ought to be enough for everybody" as the saying goes :-)</p></pre>
