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).
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 */
AVAILABILITY
Always
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 vari-
able which can be tested for NULL before updating the original list
pointer.
