Constructor & Destructor Documentation

template<typename T>

shm_queue_header< T >::shm_queue_header

(

size_t

s = 0

)

[inline]

construct a queue header with an initial size.

The queue is constructed with a head and tail with shared memory pointers containing initial offset of zero (indicating NULL). The queue tail is intially locked.

Parameters:

s

size of the queue
