NNG_HTTP_RES_GET_DATA(3http)

📦 version 1.11, in alpine 3.24

🎀 NAME 🎀

nng_http_res_get_data — get HTTP response body.

Okay bestie, welcome to NNG_HTTP_RES_GET_DATA(3http) from the NNG Reference Manual. This is the page for grabbing that HTTP body, and yes, it's exactly as iconic as it sounds. ✨

✨ SYNOPSIS ✨

#include <nng/nng.h>
#include <nng/supplemental/http/http.h>

void nng_http_res_get_data(nng_http_res *res, void **bodyp, size_t *sizep);

This is literally the whole call, no cap. 🫶

💖 DESCRIPTION 💖

So nng_http_res_get_data() gets the HTTP body associated with the request res, storing a pointer to the buffer at the location referenced by bodyp, and the length of the associated buffer at the location referenced by sizep. It's giving "two outputs, one call" energy. 💅

Note: the buffer you get back is owned by res, and it will automatically be freed when the request is freed. So it's not yours to free, bestie — that's res's job. 🔥

🌈 RETURN VALUES 🌈

None. Zero. Nada. It's a void function, so it doesn't return anything — it just fills in your bodyp and sizep and ghosts. 😭

💀 ERRORS 💀

None. No errors, no drama, no spicy failure modes listed here. 💀

👑 SEE ALSO 👑

Yep, nng_http_req_copy_data(3http) is listed twice — that's the original vibe, and I'm keeping it exactly. 💅

That's the whole page, bestie! 🫶 Signing off from NNG_HTTP_RES_GET_DATA(3http) in the NNG Reference Manual, dated 2026-01-13 — go get that HTTP body and slay. ✨💖
