NAME

       curl_pushheader_bynum - get a push header by index

SYNOPSIS

       #include <curl/curl.h>

       char *curl_pushheader_bynum(struct curl_pushheaders *h, size_t num);

DESCRIPTION

       This  is a function that is only functional within a CURLMOPT_PUSHFUNCTION(3) callback. It
       makes no sense to try to use it elsewhere and it has no function then.

       It returns the value for the header field at the given index num, for the incoming  server
       push  request  or  NULL.  The  data pointed will be freed when this callback returns.  The
       returned pointer points to a "name:value" string that will be  freed  when  this  callback
       returns.

EXAMPLE

       /* output all the incoming push request headers */
       int curl_push_callback(CURL *parent,
                              CURL *easy,
                              size_t num_headers,
                              struct curl_pushheaders *headers,
                              void *clientp)
       {
         sizt_t i = 0;
         char *field;
         do {
            field = curl_pushheader_bynum(headers, i);
            if(field)
              fprintf(stderr, "Push header: %s\n", field);
            i++;
         } while(field);
         return CURL_PUSH_OK; /* permission granted */
       }

       curl_multi_setopt(multi, CURLMOPT_PUSHFUNCTION, curl_push_callback);

AVAILABILITY
