Function Documentation

IntUDAddToPendingList()

INTSTATUS IntUDAddToPendingList	(	const QWORD	Cr3,
		const QWORD	Rip,
		const QWORD	Thread,
		INFO_UD_PENDING **	CurrentPendingUD
	)

Add a new UD to the list of pending injections.

This function will create a pending UD entry for the provided CR3, RIP, and thread ID. This will allow us later to check if we have already injected a UD for a given context, so we can avoid injecting it multiple times.

Parameters

[in]	Cr3	The Cr3.
[in]	Rip	The RIP.
[in]	Thread	The thread ID (software thread!).
[out]	CurrentPendingUD	Will contain, upon successful return, the newly allocated pending UD entry.

Return values

INT_STATUS_SUCCESS	On success.
INT_STATUS_INVALID_PARAMETER	If an invalid parameter is supplied.
INT_STATUS_INSUFFICIENT_RESOURCES	If a memory alloc fails.

IntUDGetEntry()

INFO_UD_PENDING* IntUDGetEntry	(	const QWORD	Cr3,

		const QWORD	Thread
	)

Get a UD entry for the provided Cr3, Rip and Thread ID.

Parameters

[in]	Cr3	The Cr3.
[in]	Rip	The Rip.
[in]	Thread	The thread ID (software thread!).

Returns

The pending UD entry, if one is found, or NULL if none is found.
