     16 # NAME
     17 
     18 CURLOPT_TCP_KEEPIDLE - TCP keep-alive idle time wait
     19 
     20 # SYNOPSIS
     21 
     22 ~~~c
     23 #include <curl/curl.h>
     24 
     25 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TCP_KEEPIDLE, long delay);
     26 ~~~

     28 # DESCRIPTION
     29 
     30 Pass a long. Sets the *delay*, in seconds, to wait while the connection is
     31 idle before sending keepalive probes. Not all operating systems support this
     32 option.
     33 
     34 The maximum value this accepts is 2147483648. Any larger value is capped to
     35 this amount.
