// Gosched yields the processor, allowing other goroutines to run.  It does not
// suspend the current goroutine, so execution resumes automatically.

func	Goexit()

// Breakpoint() executes a breakpoint trap.
func	Breakpoint()

// Caller reports file and line number information about function invocations on
// the calling goroutine's stack.  The argument is the number of stack frames to
// ascend, with 1 identifying the the caller of Caller.  The return values report the
// program counter, file name, and line number within the file of the corresponding
// call.  The boolean ok is false if it was not possible to recover the information.
