1. Function description
    This routine is shown in the RT_Thread system call scheduler lock

2. Use environment
    Hardware environment: development hardware platform corresponding to the project 
    Development board:      N32G457QE_EVB V1.0

3. Instructions for use
    Describe the configuration method of related modules; for example: clock, I/O, etc. 
        1. SystemClock: 144MHz
        2. GPIO: PB10 controls LED(D6) flashing; The PB15 controls LED(D17) flashing
                     Log(USART1): TX--PA9 RX--PA10 Baud rate: 115200

    Describe the test steps and phenomena of Demo 
        1. After compiling, download the program to reset and run;
        2. Connect the serial port printing tool;
        3. This example creates two threads, thread1 thread and thread2 thread. Thread2 thread has a higher priority than thread1 thread. 
            The thread1 thread will lock the scheduler, before unlock, will not switch to the thread2 thread, see the print log

4. Matters needing attention
    None.
