- .SH SYNOPSIS

- .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.
- .SH EXAMPLE
- .nf
- CURL *handle;
- struct curl_slist *slist=NULL;
- slist = curl_slist_append(slist, "pragma:");
- if (slist == NULL)
- return -1;
- curl_easy_setopt(handle, CURLOPT_HTTPHEADER, slist);
- curl_easy_perform(handle);
- curl_slist_free_all(slist); /* free the list again */
