NAME
nng_http_res_get_header - return HTTP response header
SYNOPSIS
DESCRIPTION
The nng_http_res_get_header() looks for an HTTP header key in
the response res, and returns the associated value if found,
or NULL if not found.
The value of key is case insensitive, and should not include the final
colon in an HTTP header.
For example, specifying Host or hOSt are
equivalent, whereas the value Host: will not find anything.
RETURN VALUES
HTTP header value for key, if it exists, or NULL otherwise.
ERRORS
None.
