NAME

nng_http_res_del_header - delete HTTP response header

SYNOPSIS

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

DESCRIPTION

The nng_http_res_del_header() removes all HTTP headers with the associated key from the response structure res.

This function returns 0 on success, and non-zero otherwise.

ERRORS

NNG_ENOENT	No header with the key key was present.
NNG_ENOTSUP	No support for HTTP in the library.
