CURLOPT_ACCEPTTIMEOUT_MS(3) Introduction to Library Functions

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

if(curl) {
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/path/file");

/* wait no more than 5 seconds for the FTP server to connect */
curl_easy_setopt(curl, CURLOPT_ACCEPTTIMEOUT_MS, 5000L);

curl_easy_perform(curl);
}
}

AVAILABILITY
