Subject: stat() lstat() not able to read long filename with cyrillic chars?

Hi,

First, I have read the FAQ and this mailing archive :)

Here is the problem I meet:

In a directory are placed three files using windows 8's explorer:
- a short Cyrillic filename "абваб.txt"
- a long Cyrillic filename
"абвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабвабваб.txt"
- a long Latin filename
"ababababababababababababababababababababababababababababababababababababababababababababababababababababababababababababa.txt"


From a C program compiled under Cygwin, I can obtain the corresponding
filename strings using readdir_r()...

"\320\260\320\261\320\262\320\260\320\261.txt"
"\320\260\320\261\320\262\320\260\320\261\320\262\320\260\320\261 [snipped]"
"abababababaababababa [snipped]"

... but passing these strings in turn to lstat() or stat() returns 0 as
expected for all except for the long Cyrillic filename. For for this
string a get a negative value from lstat() and stat() and errno is set
to ENOENT (while the entry is still present).

using "ls" instead of my own program gives something similar: the long
Cyrillic filename is listed but no permission, username, groupname or
data are displayed, these are replaced by question marks.

Is there something special to do and that I missed in order to read long
Cyrillic filenames from a C program under Cygwin?

Thanks for any help,

Regards,
Denis.
