CURLOPT_SERVER_RESPONSE_TIMEOUT_MS(3) Introduction to Library Functions

NAME

CURLOPT_SERVER_RESPONSE_TIMEOUT_MS - time allowed to wait for server
response

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SERVER_RESPONSE_TIMEOUT_MS,
long timeout);

DESCRIPTION

Pass a long. Causes libcurl to set a timeout period (in milliseconds)
on the amount of time that the server is allowed to take in order to
send a response message for a command before the session is
considered dead. While libcurl is waiting for a response, this value
overrides CURLOPT_TIMEOUT(3). It is recommended that if used in
conjunction with CURLOPT_TIMEOUT(3), you set
CURLOPT_SERVER_RESPONSE_TIMEOUT_MS(3) to a value smaller than
CURLOPT_TIMEOUT(3).

The maximum accepted value is 2147483648.

This is the millisecond version of
CURLOPT_SERVER_RESPONSE_TIMEOUT(3).

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 237 milliseconds */
curl_easy_setopt(curl, CURLOPT_SERVER_RESPONSE_TIMEOUT_MS, 237L);
res = curl_easy_perform(curl);

curl_easy_cleanup(curl);
}
}

AVAILABILITY

Added in curl 8.6.0

RETURN VALUE

curl_easy_setopt(3) returns a CURLcode indicating success or error.
