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 the res, including all of the related headers.

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.

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.

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.

RETURN VALUES

None.

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.
