NAME
       CURLOPT_TCP_KEEPALIVE - TCP keep-alive probing

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TCP_KEEPALIVE, long probe);

DESCRIPTION
       Pass  a long. If set to 1, TCP keepalive probes will be sent. The delay
       and  frequency  of  these  probes  can  be  controlled  by   the   CUR‐
       LOPT_TCP_KEEPIDLE(3) and CURLOPT_TCP_KEEPINTVL(3) options, provided the
       operating system supports them. Set to 0 (default behavior) to  disable
       keepalive probes

PROTOCOLS
       All

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

         /* enable TCP keep-alive for this transfer */
         curl_easy_setopt(curl, CURLOPT_TCP_KEEPALIVE, 1L);

         /* keep-alive idle time to 120 seconds */
         curl_easy_setopt(curl, CURLOPT_TCP_KEEPIDLE, 120L);

         /* interval time between keep-alive probes: 60 seconds */
         curl_easy_setopt(curl, CURLOPT_TCP_KEEPINTVL, 60L);

         curl_easy_perform(curl);
       }
