Hi everybody, hi DJ!

I have found a bug with fopen() function when I want to open a shared file
Wireshark : http://cpcdos.e-monsite.com/medias/files/fopen-freedos.png


For open test.cpc :
- With a normal request (Windows, EDIT.COM(dos), Command.com(dos), or other..) he send 0x0021 request ( offset:0x5D & 0x5E ) (Read only+Archive attribute), so he want open a file, OK !
- With a fopen request he send 0x0017 request ( offset:0x5D & 0x5E ) SO he want search a directory (+hidden, readonly+system attribute) but no a file. BAD!

There are solution for "force" fopen to open/search a file in my path string(char)? add "\n" ?


Best regards
Sébastien FAVIER

PS:

- I use GCC 4.7.3 / DJGPP for dos (Under FreeDos)

- I have all permissions

- I have test multiple combinaisons :
fopen("x:\myfile.abc, "r");
fopen("x:\\myfile.abc, "r");
fopen("x:/myfile.abc, "r");
fopen("x://myfile.abc, "r");

Or directly with server name :
fopen("\\MyServer\myfile.abc, "r");
fopen("\\\\MyServer\\myfile.abc, "r");
fopen("\\MyServer/myfile.abc, "r");
fopen("\\\\MyServer//myfile.abc, "r");
fopen("//MyServer/myfile.abc, "r");
fopen("////MyServer//myfile.abc, "r");
fopen("//MyServer\myfile.abc, "r");
fopen("////MyServer\\myfile.abc, "r");

No success.. :-(
