Returns #t if bit-string contains only 0 bits; otherwise
returns #f.
Compares the two bit string arguments and returns #t if they are the
same length and contain the same bits; otherwise returns #f.
Returns a newly allocated bit string that is the bitwise-logical negation of bit-string.
The destructive version of bit-string-not. The arguments
target-bit-string and bit-string must be bit strings of the
same length. The bitwise-logical negation of bit-string is
computed and the result placed in target-bit-string. The value of
this procedure is unspecified.
Returns a newly allocated bit string that is the bitwise-logical “and” of the arguments. The arguments must be bit strings of identical length.
Returns a newly allocated bit string that is the bitwise-logical “and” of bit-string-1 with the bitwise-logical negation of bit-string-2. The arguments must be bit strings of identical length.
Returns a newly allocated bit string that is the bitwise-logical “inclusive or” of the arguments. The arguments must be bit strings of identical length.
Returns a newly allocated bit string that is the bitwise-logical “exclusive or” of the arguments. The arguments must be bit strings of identical length.
These are destructive versions of the above operations. The arguments target-bit-string and bit-string must be bit strings of the same length. Each of these procedures performs the corresponding bitwise-logical operation on its arguments, places the result into target-bit-string, and returns an unspecified result.
