FUNCTION SMC_GetObjFromEnd : POINTER TO SMC_GEOINFO

Returns a pointer to the n-last object (start counting from the end) of the queue (poq). For N=0 the last element in the list will be returned.

task-safety: may be called from both tasks; the result however may be invalid: In case of the producer task, the output may no longer be part of the queue, in case of the consumer task, the output may no longer be the last element.
