NAME
nng_http_req_copy_data - copy HTTP request body
SYNOPSIS
DESCRIPTION
The nng_http_req_copy_data() makes a copy of body (of size size)
and sets the HTTP body for the request req to it.
The copy will be deallocated automatically when req is freed.
The copied body data will be automatically sent with the request when it
is sent using nng_http_conn_write_req().
This also updates the relevant Content-Length header of req.
| The current framework does not support sending data via chunked transfer-encoding. |
To avoid copying data, the
nng_http_req_set_data() may be used instead.
|
It is a good idea to also set the Content-Type header.
|
RETURN VALUES
This function returns 0 on success, and non-zero otherwise.
ERRORS
NNG_ENOMEM
|
Insufficient memory to perform the operation. |
NNG_ENOTSUP
|
No support for HTTP in the library. |
