The 1.9.16 tree is now back to 1.9.16p2 as far as nmbd is concerned
apart from a small change that fixes the announce type in two places.

The idea is that this file will eventually have wrappers around all
|
|
important system calls in samba. The aims are:
|
|
|
|
- to enable easier porting by putting OS dependent stuff in here
|
|
|
|
- to allow for hooks into other "pseudo-filesystems"
|
|
|
|
- to allow easier integration of things like the japanese extensions
|
|
|
|
- to support the philosophy of Samba to expose the features of
|
|
the OS within the SMB model. In general whatever file/printer/variable
|
|
expansions/etc make sense to the OS should be acceptable to Samba.
