base
Pointer to the top of the stack.
limit
Pointer to the bottom of the stack.
fc_stack
Tracks the memory for the context's stack.
intptr_t jump_fcontext( fcontext_t
* ofc, fcontext_t
* nfc, intptr_t p, bool
preserve_fpu)
Stores the current context data (stack pointer, instruction pointer,
and CPU registers) to *ofc and restores the context data
from *nfc,
which implies jumping to *nfc's execution context. The intptr_t
argument, p, is passed
to the current context to be returned by the most recent call to jump_fcontext()
in the same thread. The last argument controls if fpu registers have
to be preserved.
The third pointer argument passed to the most recent call to jump_fcontext(),
if any.
void make_fcontext( fcontext_t
* fc, void(*fn)(intptr_t))
A stack is applied to *fc before make_fcontext() is called.
Modifies *fc
in order to execute fn
when the context is activated next.
