Bit­Vectors­Cowan

Specification

Constructor

(make-bitvector [ size [ fill ] ])

Returns a newly allocated bitvector. If fill is omitted or #f, then all the bits are #f; if fill is #t, the the first size bits are #t and all other bits are #f.

Predicate

(bitvector? obj)

Returns #t if obj is a bitvector, and #f otherwise.

Bitwise operations

Same as BitwiseCowan, with appropriate name changes.
