array-in-bounds-p
array-in-bounds-p array &rest subscripts → generalized-boolean
array—an array.
Note that they needn't be valid array indices, since that would make this function a lot less interesting!subscripts—a list of integers of length equal to the rank of the array.
generalized-boolean—a generalized boolean.
17.3.0 10Returns true if the subscripts are all in bounds for array; otherwise returns false. (If array is a vector with a fill pointer, that fill pointer is ignored.)
