HttpHeadersFind

Description

Container-callback shape of the same operation, matching GenericCopyDeinit. Plumb this into VecInitWithDeepCopy so a Vec(HttpHeader) automatically deinits each entry on removal.

Parameters

Success

Returns to the caller. *(HttpHeader *)header is zeroed. Returns a pointer to the matching header inside the vector. The pointer is valid until *headers is mutated or deinitialized.

Failure

Function cannot fail. The container guarantees header is non-NULL and a valid entry slot.

Returns NULL if no header matches; *headers is unchanged.

Usage example (Cross-references)

                  (ZstrCompare(next, "body-bytes") == 0);
    
        HttpHeader *host = HttpHeadersFind(&req.headers, "Host");
        ok               = ok && host && ZstrCompare(StrBegin(&host->value), "example.com") == 0;
