Module Name: InternalSwitchStack.c Transfers control to a function starting with a new stack.

Transfers control to the function specified by EntryPoint using the new stack specified by NewStack and passing in the parameters specified by Context1 and Context2. Context1 and Context2 are optional and may be NULL. The function EntryPoint must never return. Marker will be ignored on IA-32, x64, and EBC. IPF CPUs expect one additional parameter of type VOID * that specifies the new backing store pointer.

If EntryPoint is NULL, then ASSERT(). If NewStack is NULL, then ASSERT().

Parameters:
EntryPointA pointer to function to call with the new stack.
Context1A pointer to the context to pass into the EntryPoint function.
Context2A pointer to the context to pass into the EntryPoint function.
NewStackA pointer to the new stack to use for the EntryPoint function.
MarkerVA_LIST marker for the variable argument list.

BOOLEAN EFIAPI IsNodeInList ( IN CONST LIST_ENTRY List,
IN CONST LIST_ENTRY Node 
)

Worker function that locates the Node in the List.

By searching the List, finds the location of the Node in List. At the same time, verifies the validity of this list.

If List is NULL, then ASSERT(). If List->ForwardLink is NULL, then ASSERT(). If List->backLink is NULL, then ASSERT(). If Node is NULL, then ASSERT(); If PcdMaximumLinkedListLenth is not zero, and prior to insertion the number of nodes in ListHead, including the ListHead node, is greater than or equal to PcdMaximumLinkedListLength, then ASSERT().

Parameters:
ListA pointer to a node in a linked list.
NodeA pointer to one nod.
Return values:
TRUENode is in List.
FALSENode isn't in List, or List is invalid.
