| 29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TCP_KEEPALIVE, long probe); | |
| 30 .SH DESCRIPTION | |
| 31 Pass a long. If set to 1, TCP keepalive probes will be sent. The delay and | |
| 32 frequency of these probes can be controlled by the | |
| 33 \fICURLOPT_TCP_KEEPIDLE(3)\fP and \fICURLOPT_TCP_KEEPINTVL(3)\fP options, | |
| 34 provided the operating system supports them. Set to 0 (default behavior) to | |
| 35 disable keepalive probes | |
