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

#include <stdio.h>

        FILE *fp=3DNULL;

        printf("Create file\n");
        if((fp=3Dfopen("toto","a+"))=3D=3DNULL) {
                perror("Error Create: ");
                exit(255);
        }
        printf("unlink file\n");
        ret=3Dunlink("toto");
        if (ret !=3D 0) {
                perror("Error Unlink: ");
                exit(255);
        }
        printf("Create Again the file\n");
        if((fp=3Dfopen("toto","a+"))=3D=3DNULL) {
                perror("Error Create: ");
                exit(255);
