5.1 Safe Homogenous Vectors
(require ffi/vector) |
Homogenous vectors are similar to C vectors (see Safe C Vectors), except that they define different types of vectors, each with a hard-wired type. An exception is the u8 family of bindings, which are just aliases for byte-string bindings; for example, make-u8vector is an alias for make-bytes.
(make-u8vector len) → u8vector? |
len : exact-nonnegative-integer? |
(u8vector val ...) → u8vector? |
val : number? |
(u8vector? v) → boolean? |
v : any/c |
(u8vector-length vec) → exact-nonnegative-integer? |

is the identity function.
