Module Name:

smbgtpt.h
|

|
|

|
|
Abstract:
|
||
|
|
|
||
|
|
This module defines macros for retrieving and storing SMB data.
|
||
|
|
The macros account for the misaligned nature of the SMB protocol.
|
||
|
|
They also translate from the little-endian SMB format into
|
||
|
|
big-endian format, when necessary.
