83 * GET THE NAME OF A SEMAPHORE, MUTEX, MAILBOX or QUEUE
84 *
85 * Description: This function is used to obtain the name assigned to a semaphore, mutex, mailbox or queue.
86 *
87 * Arguments : pevent is a pointer to the event group. 'pevent' can point either to a semaphore,
88 * a mutex, a mailbox or a queue. Where this function is concerned, the actual
89 * type is irrelevant.
90 *
91 * pname is a pointer to a pointer to an ASCII string that will receive the name of the semaphore,
92 * mutex, mailbox or queue.
93 *
94 * perr is a pointer to an error code that can contain one of the following values:
95 *
96 * OS_ERR_NONE if the name was copied to 'pname'
97 * OS_ERR_EVENT_TYPE if 'pevent' is not pointing to the proper event
98 * control block type.
99 * OS_ERR_PNAME_NULL You passed a NULL pointer for 'pname'
100 * OS_ERR_PEVENT_NULL if you passed a NULL pointer for 'pevent'
101 * OS_ERR_NAME_GET_ISR if you are trying to call this function from an ISR
102 *
103 * Returns : The length of the string or 0 if the 'pevent' is a NULL pointer.
