Arguments

`vector`⇩	An simple-int64-vector.
`index`⇩	A non-negative fixnum.
`int64-or-int`⇩	An int64 object or an integer of type `(signed-byte 64)`.

Values

`int64`	An int64 object.
`int64-or-int`	An int64 object or an integer of type `(signed-byte 64)`.

Description

The accessor int64-aref gets and sets the elements of a simple-int64-vector. The reader returns an int64 object for the value at index index in vector. The writer sets the value at index index in vector to the int64 object or integer int64-or-int supplied.
