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: make-u8vector, u8vector. u8vector?, u8vector-length, u8vector-ref, u8vector-set!, list->u8vector, u8vector->list.
