NAME

       curl_slist_append - add a string to an slist

SYNOPSIS

       #include <curl/curl.h>

       struct curl_slist *curl_slist_append(struct curl_slist *list, const char * string);

DESCRIPTION

       curl_slist_append(3)  appends a string to a linked list of strings. The existing list should be passed as
       the first argument and the new list is returned from this function. Pass in NULL in the list argument  to
       create   a   new   list.   The   specified   string   has  been  appended  when  this  function  returns.
       curl_slist_append(3) copies the string.

       The list should be freed again (after usage) with curl_slist_free_all(3).

RETURN VALUE

       A null pointer is returned if anything went wrong, otherwise the new list pointer is returned.  To  avoid
       overwriting  an  existing  non-empty  list  on  failure,  the  new list should be returned to a temporary
       variable which can be tested for NULL before updating the original list pointer.

EXAMPLE

       CURL *handle;
       struct curl_slist *slist=NULL;
       struct curl_slist *temp=NULL;

       slist = curl_slist_append(slist, "pragma:");

       if (slist == NULL)
         return -1;

       temp = curl_slist_append(slist, "Accept:")

       if (temp == NULL) {
         curl_slist_free_all(slist);
         return -1;
       }

       slist = temp;

       curl_easy_setopt(handle, CURLOPT_HTTPHEADER, slist);

       curl_easy_perform(handle);

       curl_slist_free_all(slist); /* free the list again */
