I'm using 0.9.29 on Atmel's AVR32-based NGW100 dev kit.
The attached code shows some strange behaviour in the glob() function.
Basically I call glob() three times
First time, globret = 0 so everything was fine
Second time, I set errno to any non-zero value and then call glob(). globret =
2 meaning that glob() failed.
Third time, I set errno back to 0. Now globret = 0 so the glob() was fine.
AFAIK, no errno should only report what *has* happenned, not affect any future
function calls. Right ?
I raised a ticket on bugs.uclibc.org on 24/07/08, but I've had no response.
Is this a known issue ? Can someone else confirm the bug ?
Regards
Mark
