NAME

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode  curl_easy_setopt(CURL  *handle,  CURLOPT_SSH_KNOWNHOSTS, char
12       *fname);
13

DESCRIPTION

15       Pass a pointer to a zero terminated string holding the file name of the
16       known_host  file  to  use.  The known_hosts file should use the OpenSSH
17       file format as supported by libssh2. If this file is specified, libcurl
18       will  only  accept connections with hosts that are known and present in
19       that file, with a matching public key.  Use  CURLOPT_SSH_KEYFUNCTION(3)
20       to alter the default behavior on host and key (mis)matching.
21
22       The  application  does not have to keep the string around after setting
23       this option.
