💅 NNG_HTTP_CONN_READ_RES(3http) — read HTTP response 💅

hii bestie 🫶 this is the NNG_HTTP_CONN_READ_RES(3http) page from the NNG Reference Manual, and we're about to read an HTTP response together. no cap, it's giving async girlie energy ✨

🌸 NAME 🌸

nng_http_conn_read_res — read HTTP response

🦋 SYNOPSIS 🦋

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

void nng_http_conn_read_res(nng_http_conn *conn, nng_http_res *res,
    nng_aio *aio);

✨ DESCRIPTION ✨

The nng_http_conn_read_res() function starts an asynchronous read from the HTTP connection conn, reading an HTTP response into res, including all of the related headers. literally the whole response envelope, bestie 💌

Note 🎀 Any HTTP entity/body data associated with the response is not read automatically. The caller should use nng_http_conn_read_all to read the entity data, based on the details of the response itself. so don't forget the body, okay? 😭

This function returns immediately, with no return value. Completion of the operation is signaled via the aio, and the final result may be obtained via nng_aio_result(). That result will either be zero or an error code. periodt. 💅

Note 🌈 Consider using the nng_http_client_transact() or nng_http_conn_transact() functions, which provide a simpler interface for performing a complete HTTP client transaction. honestly kind of iconic of them.

💖 RETURN VALUES 💖

None. yep, that's it — the result comes through the aio, not through a return value 🫶

🎀 ERRORS 🎀

  • NNG_ECANCELED — The operation was canceled. 🙈
  • NNG_ECLOSED — The connection was closed. 💀
  • NNG_ECONNRESET — The peer closed the connection. 😭
  • NNG_ENOMEM — Insufficient free memory to perform the operation. 🫠
  • NNG_ENOTSUP — HTTP operations are not supported. 🚫
  • NNG_ETIMEDOUT — Timeout waiting for data from the connection. ⏰
