<div class="textblock"><p>Single hash entry in the in-memory cache. </p>
|
|
<p>This structure is managed by uthash (open addressing with chaining semantics provided by macros). It represents one key/value association tracked by the cache. The cache implementation supports both string keys (null-terminated) and 64-bit numeric keys; numeric keys are stored by casting to a temporary string buffer upstream (see implementation). Callers do not allocate or free individual entries directly; use the cache API helpers.</p>
|
|
<p>Lifetime & ownership:</p><ul>
|
|
<li>key points either to a heap-allocated C string owned by the cache or to a short-lived buffer duplicated internally; callers must not free it after insertion.</li>
|
|
<li>value is an opaque pointer supplied by caller; the cache does not take ownership of the pointee (caller remains responsible for the underlying object unless documented otherwise). </li>
|
|
</ul>
