xMessageBufferIsFull()
[RTOS Message Buffer API]


message_buffer.h

BaseType_t xMessageBufferIsFull( MessageBufferHandle_t xMessageBuffer );

Queries a message buffer to see if it is full. A message buffer is full if it cannot accept any more messages, of any size, until space is made available by a message being removed from the message buffer.

Message buffer functionality is enabled by including the FreeRTOS/source/stream_buffer.c source file in the build (as message buffers use stream buffers).

Parameters:
xMessageBuffer   The handle of the message buffer being queried.
Returns:
If the message buffer is full then pdTRUE is returned. Otherwise pdFALSE is returned.
