## Description

## Function Documentation

void EvrRtxThreadFlagsError | ( | osThreadId_t | thread_id,
|  | int32_t | status
| ) |  |

Parameters

  [in] | thread_id | thread ID obtained by osThreadNew or osThreadGetId or NULL when ID is unknown.
  [in] | status | extended execution status.

The event ThreadFlagsError is generated when Thread Flags routines complete their execution due to an error.

The status parameter indicates the execution status and can be one of the osStatus_t codes or one of the extended execution status codes which are summarized in the table below.

Extended Status Code | Description
--- | ---
osRtxErrorKernelNotReady | Kernel scheduler is not in Ready state.
osRtxErrorKernelNotRunning | Kernel scheduler is not executing - there is no running thread.
osRtxErrorInvalidControlBlock | Object control block with invalid alignment or size was specified.
osRtxErrorInvalidDataMemory | Object data memory with invalid alignment or size was specified.
osRtxErrorInvalidThreadStack | Thread stack memory with invalid alignment or size was specified.
osRtxErrorInvalidPriority | Invalid thread priority was specified.
osRtxErrorThreadNotJoinable | Specified thread is not joinable.
osRtxErrorMutexNotOwned | Specified mutex is not owned by the current running thread.
osRtxErrorMutexNotLocked | Specified mutex is not locked.
osRtxErrorMutexLockLimit | Maximum number of recursive mutex locks reached.
osRtxErrorSemaphoreCountLimit | Semaphore count limit reached.
osRtxErrorTZ_InitContext_S | Secure context memory system initialization failed.
osRtxErrorTZ_AllocContext_S | Secure context memory allocation failed.
osRtxErrorTZ_FreeContext_S | Secure context memory deallocation failed.
osRtxErrorTZ_LoadContext_S | Secure context load failed.
osRtxErrorTZ_SaveContext_S | Secure context save failed.

Value in the Event Recorder shows:

- thread_id : thread ID.
- status : execution status code.

void EvrRtxThreadFlagsSet | ( | osThreadId_t | thread_id,
|  | uint32_t | flags
| ) |  |

Parameters

  [in] | thread_id | thread ID obtained by osThreadNew or osThreadGetId.
  [in] | flags | flags of the thread that shall be set.

The event ThreadFlagsSet is generated when the function osThreadFlagsSet is called.

Value in the Event Recorder shows:

- thread_id : thread ID.
- flags : flags that shall be set.

void EvrRtxThreadFlagsSetDone | ( | osThreadId_t | thread_id,
|  | uint32_t | thread_flags
| ) |  |

Parameters

  [in] | thread_id | thread ID obtained by osThreadNew or osThreadGetId.
  [in] | thread_flags | thread flags after setting.

The event ThreadFlagsSetDone is generated when thread flags are successfully set.

Value in the Event Recorder shows:

- thread_id : thread ID.
- thread_flags : thread flags after setting.

void EvrRtxThreadFlagsClear | ( | uint32_t | flags | ) |

Parameters

  [in] | flags | flags of the thread that shall be cleared.

The event ThreadFlagsClear is generated when the function osThreadFlagsClear is called.

Value in the Event Recorder shows:

- flags : flags that shall be cleared.

void EvrRtxThreadFlagsClearDone | ( | uint32_t | thread_flags | ) |

Parameters

  [in] | thread_flags | thread flags before clearing.

The event ThreadFlagsClearDone is generated when the function osThreadFlagsClear successfully clears thread flags.

Value in the Event Recorder shows:

- thread_flags : thread flags before clearing.

void EvrRtxThreadFlagsGet | ( | uint32_t | thread_flags | ) |

Parameters

  [in] | thread_flags | current thread flags.

The event ThreadFlagsGet is generated when the function osThreadFlagsGet is called and its execution result is known.

Value in the Event Recorder shows:

- thread_flags : current thread flags.

void EvrRtxThreadFlagsWait | ( | uint32_t | flags,
|  | uint32_t | options,
|  | uint32_t | timeout
| ) |  |

Parameters

  [in] | flags | flags to wait for.
  [in] | options | flags options (osFlagsXxxx).
  [in] | timeout | Timeout Value or 0 in case of no time-out.

The event ThreadFlagsWait is generated when the function osThreadFlagsWait is called.

Value in the Event Recorder shows:

- flags : flags to wait for.
- options : flags options (refer to thread flags options).
- timeout : Timeout Value.

void EvrRtxThreadFlagsWaitPending | ( | uint32_t | flags,
|  | uint32_t | options,
|  | uint32_t | timeout
| ) |  |

Parameters

  [in] | flags | flags to wait for.
  [in] | options | flags options (osFlagsXxxx).
  [in] | timeout | Timeout Value or 0 in case of no time-out.

The event ThreadFlagsWaitPending is generated when the function osThreadFlagsWait starts waiting for thread flags to become signaled.

Value in the Event Recorder shows:

- flags : flags to wait for.
- options : flags options (refer to thread flags options).
- timeout : Timeout Value.

void EvrRtxThreadFlagsWaitTimeout | ( | osThreadId_t | thread_id | ) |

Parameters

  [in] | thread_id | thread ID obtained by osThreadNew or osThreadGetId.

The event ThreadFlagsWaitTimeout is generated when wait for thread flags to become signaled is aborted due to expired wait timeout.

Value in the Event Recorder shows:

- thread_id : thread ID.

void EvrRtxThreadFlagsWaitCompleted | ( | uint32_t | flags,
|  | uint32_t | options,
|  | uint32_t | thread_flags,
|  | osThreadId_t | thread_id
| ) |  |

Parameters

  [in] | flags | flags to wait for.
  [in] | options | flags options (osFlagsXxxx).
  [in] | thread_flags | thread flags before clearing.
  [in] | thread_id | thread ID obtained by osThreadNew or osThreadGetId.

The event ThreadFlagsWaitCompleted is generated when waiting for thread flags ends because requested flags were signaled.

Value in the Event Recorder shows:

- flags : flags thread was waiting for.
- option : flags options (refer to thread flags options).
- thread_flags : thread flags before clearing.
- thread_id : thread ID.

void EvrRtxThreadFlagsWaitNotCompleted | ( | uint32_t | flags,
|  | uint32_t | options
| ) |  |

Parameters

  [in] | flags | flags to wait for.
  [in] | options | flags options (osFlagsXxxx).

The event ThreadFlagsWaitNotCompleted is generated when the function osThreadFlagsWait returns without timeout and specified thread flags were not signaled.

Value in the Event Recorder shows:

- flags : flags thread was waiting for.
- options : flags options (refer to thread flags options).
