NAME

6       curl_pushheader_bynum - get a push header by index
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       char *curl_pushheader_bynum(struct curl_pushheaders *h, size_t num);
12

DESCRIPTION

14       This  is a function that is only functional within a CURLMOPT_PUSHFUNC‐
15       TION(3) callback. It makes no sense to try to use it elsewhere  and  it
16       has no function then.
17
18       It  returns  the value for the header field at the given index num, for
19       the incoming server push request or NULL.  The  data  pointed  will  be
20       freed  when  this  callback  returns.  The returned pointer points to a
21       "name:value" string that will be freed when this callback returns.

EXAMPLE

25       /* output all the incoming push request headers */
26       int curl_push_callback(CURL *parent,
27                              CURL *easy,
28                              size_t num_headers,
29                              struct curl_pushheaders *headers,
30                              void *clientp)
31       {
32         sizt_t i = 0;
33         char *field;
34         do {
35            field = curl_pushheader_bynum(headers, i);
36            if(field)
37              fprintf(stderr, "Push header: %s\n", field);
38            i++;
39         } while(field);
40         return CURL_PUSH_OK; /* permission granted */
41       }
42
43       curl_multi_setopt(multi, CURLMOPT_PUSHFUNCTION, curl_push_callback);
