Functions
BaseType_t xQueueGenericSend(QueueHandle_t
It is preferred that the macros xQueueSend(), xQueueSendToFront() and xQueueSendToBack() are used in
place of calling this function directly.
Post an item on a queue. The item is queued by copy, not by reference. This function must not be called from
an interrupt service routine. See xQueueSendFromISR () for an alternative which may be used in an ISR.
Example usage:
struct AMessage
{
char ucMessageID;
char ucData[ 20
} xMessage;
uint32_t ulVar
void vATask( void *pvParameters )
{
QueueHandle_t xQueue1, xQueue2;
struct AMessage *pxMessage;
// Create a queue capable of containing
xQueue1 = xQueueCreate( 10, sizeof( uint32_t ) );
// Create a queue capable of containing
// These should be passed by pointer
xQueue2 = xQueueCreate( 10, sizeof( struct AMessage
// ...
