CURLOPT_ACCEPTTIMEOUT_MS(3) Library Functions Manual
NAME
CURLOPT_ACCEPTTIMEOUT_MS - timeout waiting for FTP server to connect
back
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ACCEPTTIMEOUT_MS, long ms);
DESCRIPTION
Pass a long telling libcurl the maximum number of milliseconds to wait
for a server to connect back to libcurl when an active FTP connection
is used. When active FTP is used, the client (libcurl) tells the server
to do a TCP connect back to the client, instead of vice versa for
passive FTP.
This option has no purpose for passive FTP.
DEFAULT
60000 milliseconds

curl_easy_setopt(curl, CURLOPT_ACCEPTTIMEOUT_MS, 5000L);
curl_easy_perform(curl);
}
}
