	Type by which queues are referenced. More...
typedef void *	QueueSetHandle_t
	Type by which queue sets are referenced. More...
typedef void *	QueueSetMemberHandle_t
	Queue sets can contain both queues and semaphores, so the QueueSetMemberHandle_t is defined as a type to be used where a parameter or return value can be either an QueueHandle_t or an SemaphoreHandle_t. More...

typedef void* QueueHandle_t

Type by which queues are referenced.

For example, a call to xQueueCreate() returns an QueueHandle_t variable that can then be used as a parameter to xQueueSend(), xQueueReceive(), etc.

typedef void* QueueSetHandle_t

Type by which queue sets are referenced.

For example, a call to xQueueCreateSet() returns an xQueueSet variable that can then be used as a parameter to xQueueSelectFromSet(), xQueueAddToSet(), etc.

typedef void* QueueSetMemberHandle_t

Queue sets can contain both queues and semaphores, so the QueueSetMemberHandle_t is defined as a type to be used where a parameter or return value can be either an QueueHandle_t or an SemaphoreHandle_t.
