NAME

6       ne_get_response_header, ne_response_header_iterate - functions to
7       access response headers
8

SYNOPSIS

10       #include <ne_request.h>
11
12       const char *ne_get_response_header(ne_request *request,
13                                          const char *name);
14
15       void *ne_response_header_iterate(ne_request *request, void *cursor,
16                                        const char **name,
17                                        const char **value);

DESCRIPTION

20       To retrieve the value of a response header field, the
21       ne_get_response_header function can be used, and is given the name of
22       the header to return.
23
24       To iterate over all the response headers returned, the
25       ne_response_header_iterate function can be used. This function takes a
26       cursor parameter which should be NULL to retrieve the first header. The
27       function stores the name and value of the next header header in the
28       name and value parameters, and returns a new cursor pointer which can
29       be passed to ne_response_header_iterate to retrieve the next header.
30

RETURN VALUE

32       ne_get_response_header returns a string, or NULL if no header with that
33       name was given. If used during request processing, the return value
34       pointer is valid only until the next call to ne_begin_request, or else,
35       until the request object is destroyed.
36
37       Likewise, the cursor, names, and values returned by
38       ne_response_header_iterate are only valid until the next call to
39       ne_begin_request or until the request object is destroyed.
40

EXAMPLES

42       The following code will output the value of the Last-Modified header
43       for a resource:
44
45           ne_request *req = ne_request_create(sess, "GET", "/foo.txt");
46           if (ne_request_dispatch(req) == NE_OK) {
47               const char *mtime = ne_get_response_header(req, "Last-Modified");
48               if (mtime) {
49                   printf("/foo.txt has last-modified value %s\n", mtime);
50               }
51           }
52           ne_request_destroy(req);
