The original form of the pattern, appearing in Pattern Languages of Program Design 3, [2] has data races, depending on the memory model in use, and it is hard to get right. Some consider it to be an anti-pattern. [3] There are valid forms of the pattern, including the use of the volatile keyword in Java and explicit memory barriers in C++. [4]
The triangle mate involves a queen, supported by a rook on the same file two squares away, delivering checkmate to a king that is either at the edge of the board or whose escape is blocked by a piece; the queen, rook, and king together form a triangular shape, hence the name of the mating pattern.
Philidor's mate, also known as Philidor's legacy, is a checkmating pattern that ends in smothered mate. This method involves checking with the knight forcing the king out of the corner of the board, moving the knight away to deliver a double check from the queen and knight, sacrificing the queen to force the rook next to the king, and mating with the knight.
The chess machine is an ideal one to start with, since: (1) the problem is sharply defined both in allowed operations (the moves) and in the ultimate goal (checkmate); (2) it is neither so simple as to be trivial nor too difficult for satisfactory solution; (3) chess is generally considered to require "thinking" for skillful play; a solution of ...
The language specification defines a statement as a chunk of syntax that is terminated by a ";". The language spec then says that "execution of the program proceeds one statement after the other, in sequence". Those words: "execution of the program proceeds one statement after the other, in sequence" are one piece of the execution model of C.

ICPP leads to fewer context switches as blocking is prior to first execution [2] ICPP requires more priority movements as this happens with all resource usage [2] OCPP changes priority only if an actual block has occurred [2] ICPP is called "Ceiling Locking" in Ada, "Priority Protect Protocol" in POSIX and "Priority Ceiling Emulation" in RTSJ.
