.SH DESCRIPTION
-curl_slist_append() appends a specified string to a linked list of
-strings. The existing \fIlist\fP should be passed as the first argument while
-the new list is returned from this function. The specified \fIstring\fP has
-been appended when this function returns. curl_slist_append() copies the
-string.
+\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.
