SYNOPSIS
#include <nng/nng.h>
#include <nng/supplemental/http/http.h>
void nng_http_conn_read_req(nng_http_conn *conn, nng_http_req *req,
nng_aio *aio);DESCRIPTION
The nng_http_conn_read_req() function starts an asynchronous read from the
HTTP connection conn, reading an HTTP request into the req, including all
of the related headers.
| Any HTTP entity/body data associated with the request is not read
automatically.
The caller should use nng_http_conn_read_all()to read the entity data, based on the details of the request 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.
RETURN VALUES
None.
