Declare statically a queue for the platform and initialize its data.

Parameters

[in,out]	queue_ptr	a pointer to a _ewf_platform_queue structure that will be made to point to the statically declared queue
[in]	queue_name_symb	a symbol that will be used to uniquely declare and name the queue
[in]	item_type	type queue item type
[in]	item_count	the maximum number item the queue can contain
