- Transfers control to a function starting with a new stack.\r
-\r
- Transfers control to the function specified by EntryPoint using the new stack\r
- new stack specified by NewStack and passing in the parameters specified\r
- by Context1 and Context2. Context1 and Context2 are optional and may\r
- be NULL. The function EntryPoint must never return. This function\r
- supports a variable number of arguments following the NewStack parameter.\r
- These additional arguments are ignored on IA-32, x64, and EBC.\r
- IPF CPUs expect one additional parameter of type VOID * that specifies\r
- the new backing store pointer.\r
-\r
- If EntryPoint is NULL, then ASSERT().\r
- If NewStack is NULL, then ASSERT().\r

- @param Context2 A pointer to the context to pass into the EntryPoint\r
