extern

Event on stream buffer receive when buffer is empty and receiving task is blocked (Op)

Parameters
[in]pxStreamBufferpointer to Stream Buffer object handle.

The event StreamBufferBlockingOnReceive is generated when Stream Buffer receive is blocked to wait for data to be available.

Value in the Event Recorder shows:

  • pxStreamBuffer : pointer to Stream Buffer object handle.

◆ EvrFreeRTOSStreamBuf_StreamBufferBlockingOnSend()

void EvrFreeRTOSStreamBuf_StreamBufferBlockingOnSend ( StreamBuffer_t pxStreamBuffer)
extern

Event on stream buffer send when buffer is full and sending task is blocked (Op)

Parameters
[in]pxStreamBufferpointer to Stream Buffer object handle.

The event StreamBufferBlockingOnSend is generated when Stream Buffer send is blocked to wait for free space in the buffer.

Value in the Event Recorder shows:

  • pxStreamBuffer : pointer to Stream Buffer object handle.

extern

Event on unsuccessful stream buffer object create (Error)

Parameters
[in]uxIsMessageBufferbuffer type designator (0:stream, 1:message).

The event StreamBufferCreateFailed is generated when Stream Buffer or Message Buffer object create fails due to insufficient heap memory.

Value in the Event Recorder shows:

  • uxIsMessageBuffer : buffer type designator, 0 for stream buffer and 1 for message buffer.

Parameters
[in]pxStreamBufferpointer to Stream Buffer object handle.
[in]uxIsMessageBufferbuffer type designator (0:stream, 1:message).

The event StreamBufferCreateStaticFailed is generated when statically allocated Stream Buffer or Message Buffer object fails to initialize.

Value in the Event Recorder shows:

  • pxStreamBuffer : pointer to statically allocated Stream Buffer object handle.
  • uxIsMessageBuffer : buffer type designator, 0 for stream buffer and 1 for message buffer.

◆ EvrFreeRTOSStreamBuf_StreamBufferDelete()

void EvrFreeRTOSStreamBuf_StreamBufferDelete ( StreamBuffer_t pxStreamBuffer)
extern

Event on stream buffer object delete (Op)

Parameters
