+.TH gnurl_slist_append 3 "19 Jun 2003" "libcurl 7.10.4" "libgnurl Manual"
+.SH NAME
+curl_slist_append - add a string to an slist
+.SH SYNOPSIS
+.B #include <gnurl/curl.h>
+.sp
+.BI "struct curl_slist *curl_slist_append(struct curl_slist *" list,
+.BI "const char * "string ");"
+.ad
+.SH DESCRIPTION
+\fIcurl_slist_append(3)\fP appends a string to a linked list of strings. The
+existing \fBlist\fP should be passed as the first argument and the new list is
+returned from this function. Pass in NULL in the \fBlist\fP argument to create
+a new list. The specified \fBstring\fP has been appended when this function
+returns. \fIcurl_slist_append(3)\fP copies the string.
+
+The list should be freed again (after usage) with
+\fIcurl_slist_free_all(3)\fP.
+.SH 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.
+.SH EXAMPLE
+.nf
+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 */
