# CURLOPT\_SERVER\_RESPONSE\_TIMEOUT(3)

time allowed to wait for server response

## NAME

CURLOPT\_SERVER\_RESPONSE\_TIMEOUT - time allowed to wait for server response

## SYNOPSIS

```
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SERVER_RESPONSE_TIMEOUT,
                          long timeout);
```

## DESCRIPTION

Pass a long. It tells libcurl to wait no longer than *timeout* seconds for responses on sent commands. If no response is received within this period, the connection is considered dead and the transfer fails.

It is recommended that if used in conjunction with *[CURLOPT\_TIMEOUT(3)](/CURLOPT_TIMEOUT/3.md)*, you set *[CURLOPT\_SERVER\_RESPONSE\_TIMEOUT(3)](/CURLOPT_SERVER_RESPONSE_TIMEOUT/3.md)* to a value smaller than *[CURLOPT\_TIMEOUT(3)](/CURLOPT_TIMEOUT/3.md)*.

## DEFAULT

60 seconds

## PROTOCOLS

This functionality affects ftp, imap, pop3, scp, sftp and smtp

## EXAMPLE

```
int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    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);
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
```

## HISTORY

This option was formerly known as CURLOPT\_FTP\_RESPONSE\_TIMEOUT.

## AVAILABILITY

Added in curl 7.20.0

## RETURN VALUE

*[curl\_easy\_setopt(3)](/curl_easy_setopt/3.md)* returns a CURLcode indicating success or error.

CURLE\_OK (0) means everything was OK, non-zero means an error occurred, see *[libcurl-errors(3)](/libcurl-errors/3.md)*.
