CURLOPT_SERVER_RESPONSE_TIMEOUT_MS(3) | Library Functions Manual | CURLOPT_SERVER_RESPONSE_TIMEOUT_MS(3) |
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. It tells libcurl to wait no longer than timeout milliseconds 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), 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.
CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
