New Revision: 64754
URL: http://svn.reactos.org/svn/reactos?rev=64754&view=rev
Log:
[NTFS]
- Implement NtfsGetNameInformation()
- Implement NtfsGetDirectoryInformation()
- Implement NtfsGetFullDirectoryInformation()
- Implement NtfsGetBothDirectoryInformation()
- Implement NtfsQueryDirectory() which makes use of all the functions upper + all the
previous fixes to make it able to look for a file using WC and file entry index
This is supposed to bring directory enumeration in line on NTFS volumes. BUT, there's
a bug at some point which makes it fail (or my test volume is corrupted :-P (which is
unlikely (Scheme, get out of this commit message!))). Will look into it later on.
Committing so far because it's quite major work anyway.
More to follow~
