#include <rw/itc/RWTPCPtrStack.h> 

RWTPCPtrStack<Type> is a last-in-first-out (LIFO) stack that provides producer-consumer synchronization semantics for exchanging pointer values between cooperating threads.

In the producer-consumer synchronization model, reader threads (consumers) are blocked while the stack is empty, and writer threads (producers) are blocked while the stack is full. A buffer is considered full when the number of unread entries equals or exceeds some user-specified maximum capacity.

See RWTPCValQueue<Type> for a producer-consumer example.

RWTPCPtrStack(size_t maxCapacity=0, bool isOpen=true);

Constructs a pointer-based producer-consumer stack instance.

The parameter maxCapacity specifies the maximum number of unread entries allowed to accumulate within the stack. Once the number of entries in the stack equals this number, any thread attempting to write an additional entry is blocked until an entry is removed by a read operation, or until the capacity is increased. A capacity of zero, the default, is used to indicate that the stack has no size limit, except as imposed by memory limitations, and that all write operations should complete without blocking.

The parameter isOpen is a bool value that specifies whether the stack should be initialized in the open state (true, the default) or the closed state (false).
