/* __getcontext (const ucontext_t *ucp)

|
Saves the machine context in UCP such that when it is activated,
|
|
it appears as if __getcontext() returned again. The only difference
|
|
is that on a first return, %r2 contains 1 and on a subsequent
|
|
return, it contains 0.
|
|
|
|
This implementation is intended to be used for *synchronous* context
|
|
switches only. Therefore, it does not have to save anything
|

other than the PRESERVED state. */
