We begin by creating a queue containing a single Wa i t Pa i r entry This first pair tracks the current thread whose attempted acquisition of t a rget Loc k is triggering detection to kick in (Alternative algorithms involve start ing with all threads that hold locks and attempting to find any cycle The one shown only finds cycles that are rooted with a specific acquire This is slightly more efficient) We then enter a wh i l e loop We omit a slight opti mization for code brevity: if t a rget Loc k has no owner, there is no need to allocate any lists The initial pair is stored inside a variable c u r rent, which will always hold the most recent pair in the wait graph Once inside the while loop, we first see whether the current pair's lock has an owner If the lock is not held by another thread, there is no cycle and we return out of the method Otherwise, we check whether the owner is inside the wait graph If we've seen the thread previously, we have found a cycle and, therefore, can report a deadlock What we do is very specific to the scenario: we may print some diagnostics and wait anyway, commu nicate the information through a debugger, throw an exception, and so on Next, if we have not found a cycle, we continue We check what lock the owner is waiting to acquire If the owner isn't waiting, it's making forward progress under the lock, and we can safely exit knowing there are no dead locks Otherwise, we produce a new pair, set it as the current, and add it to the wait graph We then go back around the loop and continue until we find a deadlock or are convinced there aren't any In effect, we're building a graph like the one shown in Figure 1 1 2 The boxes indicate threads and the circles indicate locks; a line from a box to a circle means the thread is waiting for that lock, and a line from a circle to a box means that lock is owned by that particular thread.

considered to be negative, and the rest of the number must be specified in two's compliment representation Unless you enjoy thinking about binary representation in your code, the easiest approach to getting a negative value into a F I L ETIME structure is to use a 64-bit data type and copy by hand the high and low bits back into the F I L ETIME's dwH i g h DateTime and dwLowDateTime parts, respectively Here is a simple function that does all of the bit-blitting for us It takes a pointer to a F I L ETIME and number of milliseconds, specified as a DWO RD, and initializes the F I L ETIME's fields

Signaling an Object and Waiting Atomically Recall Table 51 from earlier in this chapter that some kernel objects are sig naled only by the kernel-such as the process and thread objects-and that programs have little direct control over transitions between the signaled and nonsignaled states Many other objects, such as those meant for syn chronization, require you to manually trigger the transitions using object specific and wait APIs S i g n a l O b j ectAndWait is alternative way to signal these kinds of objects directly

The payroll function requires a significant amount of recordkeeping, primarily under the regulations of the Internal Revenue Service and the Fair Labor Standards Act; other federal and state laws require some additional record storage The core recordkeeping area involves basic employee contact information, wages paid, and tax withholdings Layered on top of this information are storage requirements pertaining to the verification of employee eligibility to work, unemployment pay, garnishments, leaves of absence, and unclaimed wages Details about each of these areas are discussed in this chapter We also address the time periods over which documents should be retained and the proper procedures to use for planned document destruction

This API accommodates situations in which you must signal an object and begin waiting for another one atomically Although this isn' t overly common, it's not rare either: there are many interesting cases in which it's a requirement for avoiding missed wake-ups and corresponding dead locks We'll see such a case shortly Condition variables offer first class
