bytevector=? - compare two bytevectors
LIBRARY
(import (rnrs)) ;R6RS
(import (rnrs bytevectors)) ;R6RS
SYNOPSIS
(bytevector=? bytevector1 bytevector2)
DESCRIPTION
Returns
#t
if
bytevector1
and
bytevector2
are equal. They are equal
if they have the same length and equal bytes at all valid
indices. It returns
#f
otherwise.
RETURN VALUES
Returns a single boolean object.
EXAMPLES
(bytevector=? #vu8(1 2 3) #vu8(1 2 3)) => #t
(bytevector=? #vu8(1 2 3) #vu8(0 1 2)) => #f
APPLICATION USAGE
Programs that work with sensitive data such as passwords and message
digests must never use this procedure with attacker-controlled data.
It may leak information through the time it takes to execute, leading
to the movie trope where a password is cracked one letter at a time.
COMPATIBILITY
This procedure is absent from R7RS. Use
equal?(3scm)
instead.
ERRORS
This procedure can raise exceptions with the following condition types:
- &assertion (R6RS)
-
The wrong number of arguments was passed or an argument was outside its domain.
SEE ALSO
