The default is nil . The default is nil . The default is nil . The default is 0 . If dimensions is nil then a zero-dimensional array is created.
Dimensions represents the dimensionality of the new array .
The numbers of levels in the structure must equal the rank of array . Each leaf of the nested structure must be of the type given by element-type . If fill-pointer is t , the length of the vector is used to initialize the fill pointer . If fill-pointer is an integer , it becomes the initial fill pointer for the vector . In that case, the consequences are undefined if the actual array element type of displaced-to is not type equivalent to the actual array element type of the array being created.
