Hi
I kow that several persons have sent a mail concerning this problem, but=20
unfortunately I don't see a clear solution in the mailing list.
It seems to me very strange because this kind of code happens very often .
My problem is that we can't recreate a file immediately after an=20
unlink() of this file.I have a permission denied.
Here is my test program testop.c. When I execute it :
$ ./testop
Create file
unlink file
Create Again the file
Error Create: : Permission denied
Thanks in advance for your help
Best regards
Martine
