* GET THE NAME OF A SEMAPHORE, MUTEX, MAILBOX or QUEUE
*
* Description: This function is used to obtain the name assigned to a semaphore, mutex, mailbox or queue.
*
* Arguments : pevent is a pointer to the event group. 'pevent' can point either to a semaphore,
* a mutex, a mailbox or a queue. Where this function is concerned, the actual
* type is irrelevant.
*
* pname is a pointer to an ASCII string that will receive the name of the semaphore,
* mutex, mailbox or queue. The string must be able to hold at least
* OS_EVENT_NAME_SIZE characters.
*
* perr is a pointer to an error code that can contain one of the following values:
*
* OS_ERR_NONE if the name was copied to 'pname'
* OS_ERR_EVENT_TYPE if 'pevent' is not pointing to the proper event
* control block type.
* OS_ERR_PNAME_NULL You passed a NULL pointer for 'pname'
* OS_ERR_PEVENT_NULL if you passed a NULL pointer for 'pevent'
*
* Returns : The length of the string or 0 if the 'pevent' is a NULL pointer.

温馨提示
在stm32f103上移植的ucosii程序,直接操作寄存器方式,没有使用stm的库 简单易懂,下过去就可以使用,跑通多任务,用systick作为系统的时钟节拍,用PendSV_Handler中断来调度任务
