bytevector? - test if an object is a bytevector
LIBRARY
(import (rnrs)) ;R6RS
(import (rnrs bytevectors)) ;R6RS
(import (scheme base)) ;R7RS
SYNOPSIS
(bytevector? obj)
DESCRIPTION
Returns #t if obj is a bytevector, otherwise returns #f.
RETURN VALUES
Returns a single boolean object as per the description.
EXAMPLES
(bytevector? #vu8(1 2 3)) => #t ; R6RS
(bytevector? #u8(1 2 3)) => #t ; R7RS
(bytevector? "123") => #f
(bytevector? '#(1 2 3)) => #f
COMPATIBILITY
Bytevectors are a disjoint type in both R6RS and R7RS. This is
specified in R6RS standard libraries § 2 and in R7RS § 3.2.
ERRORS
This procedure can raise exceptions with the following condition types:
- &assertion (R6RS)
-
The wrong number of arguments was passed.
- R7RS
-
The assertions described above are errors.
Implementations may signal an error, extend the procedure's
domain of definition to include such arguments,
or fail catastrophically.
