/** | |
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. | |
If EntryPoint is NULL, then ASSERT(). | |
If NewStack is NULL, then ASSERT(). | |
@param EntryPoint A pointer to function to call with the new stack. | |
@param Context1 A pointer to the context to pass into the EntryPoint | |
function. | |
@param Context2 A pointer to the context to pass into the EntryPoint | |
function. | |
@param NewStack A pointer to the new stack to use for the EntryPoint | |
function. | |
