wow64log.c
|
|

|
Abstract:
|
|
|
|
Main entrypoints for wow64log.dll. To add a data type handler :
|
|
1- Define a LOGDATATYPE for the data to log in w64logp.h
|
|
2- Implement the data type handler using the standard interface
|
|
NTSTATUS
|
|
LogDataType(IN OUT PLOGINFO LogInfo,
|
|
IN ULONG_PTR Data,
|
|
IN PSZ FieldName,
|
|
IN BOOLEAN ServiceReturn);
|
|
3- Insert the handler into LogDataType[] below.
