_array-header : ctype?

_array-header-pointer : ctype?

_array-header-pointer/null : ctype?

C structure type holding an APR array header.

(array-header? obj) → any

obj : any/c

Checks whether the given obj is a pointer to an APR array header.

(make-array-header   pool             element-size             element-count             allocation-count             elements)   →   array-header?

pool : pool?

element-size : exact-integer?

element-count : exact-integer?

allocation-count : exact-integer?

elements : cpointer?

Creates an APR array header from the given fields.

This procedure is unsafe.

(array-header-pool header) → pool?   header : array-header?

(array-header-element-size header) → exact-integer?   header : array-header?

(array-header-element-count header) → exact-integer?   header : array-header?

(array-header-allocation-count header) → exact-integer?   header : array-header?

(array-header-elements header) → exact-integer?   header : array-header?

Accessors for the fields of an APR array header.

The array-header-pool procedure is unsafe.

(array-header->cvector header type) → list?

header : array-header?

type : ctype?

Converts the native data pointed to by the given header into an FFI vector object with the given element type.

If the element size in the array header doesn’t match the size of the given foreign type, a type error is raised.

This procedure is unsafe.
