BaseType_t xStreamBufferReset( StreamBufferHandle_t xStreamBuffer );

Parameters
xStreamBufferThe handle of the stream buffer being reset.
Returns
If the stream buffer is reset then pdPASS is returned. If there was a task blocked waiting to send to or read from the stream buffer then the stream buffer is not reset and pdFAIL is returned.
