.TH curl_slist_append 3 "19 Jun 2003" "libcurl 7.10.4" "libcurl Manual"
.SH NAME
curl_slist_append - add a string to an slist
.SH SYNOPSIS
.B #include <curl/curl.h>
.sp
.BI "struct curl_slist *curl_slist_append(struct curl_slist *" list,
.BI "const char * "string ");"
.ad
.SH DESCRIPTION
curl_slist_append() appends a specified string to a linked list of
2003-02-21 23:19:50 +08:00
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.
2003-02-21 23:19:50 +08:00
The list should be freed again (after usage) with
\fBcurl_slist_free_all(3)\fP.
.SH RETURN VALUE
A null pointer is returned if anything went wrong, otherwise the new list
pointer is returned.
