Function Documentation

void anonymous_namespace{md_stack.h}::SwitchStack	(	vaddr_t	stackAddr,
		StackEntryFunc	entryFunc,
		void *	arg = 0
	)		[inline]

Switch stack to new location.

Control is immediately transferred to the provided entry point. Returning from the new entry point is not possible so the application should ensure that all necessary information is passed to the new context.

Parameters:

stackAddr	Address of the new stack bottom. It is actually the address past the last byte of available stack space. The stack will grow down from this location.
entryFunc	Function which should be called after the stack is switched. It is not possible to return from this function.
arg	Argument to pass to entry function entryFunc.
