* @brief This function will suspend the specified thread and change it to suspend state.
*
* @note This function ONLY can suspend current thread itself.
* rt_thread_suspend(rt_thread_self());
*
* Do not use the rt_thread_suspend to suspend other threads. You have no way of knowing what code a
* thread is executing when you suspend it. If you suspend a thread while sharing a resouce with
* other threads and occupying this resouce, starvation can occur very easily.
*
* @param thread the thread to be suspended.
* @param susp_list the list thread enqueued to. RT_NULL if no list.
* @param ipc_flags is a flag for the thread object to be suspended. It determines how the thread is suspended.
* The flag can be ONE of the following values:
* RT_IPC_FLAG_PRIO The pending threads will queue in order of priority.
* RT_IPC_FLAG_FIFO The pending threads will queue in the first-in-first-out method
* (also known as first-come-first-served (FCFS) scheduling strategy).
* NOTE: RT_IPC_FLAG_FIFO is a non-real-time scheduling mode. It is strongly recommended to use
* RT_IPC_FLAG_PRIO to ensure the thread is real-time UNLESS your applications concern about
* the first-in-first-out principle, and you clearly understand that all threads involved in
* this semaphore will become non-real-time threads.
* @param suspend_flag status flag of the thread to be suspended.
*
* @return Return the operation status. If the return value is RT_EOK, the function is successfully executed.
* If the return value is any other values, it means this operation failed.
