Types

Type-integer-listp

Check if a list of types consists of all integer types.

Signature
(type-integer-listp x) → std::bool

This is an ordinary std::deflist. It is "loose" in that it does not care whether x is nil-terminated.

Definitions and Theorems

Function: type-integer-listp

(defun type-integer-listp (x)
  (declare (xargs :guard (type-listp x)))

    (if (consp x)
        (and (type-integerp (car x))

Theorem: type-integer-listp-of-type-list-fix-x
