CURLOPT_SE...NSE_TIMEOUT(3) Library Functions ManualCURLOPT_SE...NSE_TIMEOUT(3)
NAME
CURLOPT_SERVER_RESPONSE_TIMEOUT - time allowed to wait for server re-
sponse
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SERVER_RESPONSE_TIMEOUT,
long timeout);
DESCRIPTION
Pass a long. Causes libcurl to set a timeout period (in seconds) on the
amount of time that the server is allowed to take in order to send a re-
sponse message for a command before the session is considered dead.
While libcurl is waiting for a response, this value overrides CUR-
LOPT_TIMEOUT(3). It is recommended that if used in conjunction with CUR-
LOPT_TIMEOUT(3), you set CURLOPT_SERVER_RESPONSE_TIMEOUT(3) to a value
smaller than CURLOPT_TIMEOUT(3).
This option was formerly known as CURLOPT_FTP_RESPONSE_TIMEOUT.
DEFAULT
None
PROTOCOLS
This functionality affects ftp, imap, pop3, scp, sftp and smtp
EXAMPLE
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/slow.txt");
/* wait no more than 23 seconds */
curl_easy_setopt(curl, CURLOPT_SERVER_RESPONSE_TIMEOUT, 23L);
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
AVAILABILITY
Added in curl 7.20.0
RETURN VALUE
