When I use NSFileManager's copyPath: toPath: handler: to copy a directory,
it returns with a NO. The problem lies in changeFileAttributes: atPath:
The function utime() is used to set the last modification time, but on
Windows directories don't have a modification time. So this always results
in an error.
date = [attributes objectForKey: NSFileModificationDate];
if (date)
{
BOOL ok = NO;
struct stat sb;
#if defined(__WIN32__) || defined(_POSIX_VERSION)
struct utimbuf ub;
#else
time_t ub[2];
#endif
if (stat(cpath, &sb) != 0)
ok = NO;
else
{
#if defined(__WIN32__) || defined(_POSIX_VERSION)
ub.actime = sb.st_atime;
ub.modtime = [date timeIntervalSince1970];
ok = (utime(cpath, &ub) == 0); // <-- Here is the error
// It sets errno=EACCES
// when used on directories
// or read-only files
#else
ub[0] = sb.st_atime;
ub[1] = [date timeIntervalSince1970];
ok = (utime((char*)cpath, ub) == 0);
#endif
}
if (ok == NO)
{
allOk = NO;
str = [NSString stringWithFormat:
@"Unable to change NSFileModificationDate to '%@'", date];
ASSIGN(_lastError, str);
}
}
