Module Name:

|

|
|
imgdt.cpp
|
||
|
|
|
||
|
|
Abstract:
|
||
|
|
|
||
|
|
Tool to manipulate the link date/time
|
||
|
|
stamp in binaries
|
||
|
|
|
||
|
|
NOTE : For I386/IA64 binaries only.
|
||
|
|
|
||
|
|
MappedFile abstracts the mapped binary
|
||
|
|
file in the memory and has methods to
|
||
|
|
get and set link datetime stamp. While
|
||
|
|
setting the datetime stamp it also
|
||
|
|
recomputes and updates the new checksum.
