CURLOPT_TIMEOUT(3)         curl_easy_setopt options         CURLOPT_TIMEOUT(3)

NAME
       CURLOPT_TIMEOUT - set maximum time the request is allowed to take

SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       Pass a long as parameter containing timeout - the maximum time in  sec-
       onds  that  you allow the libcurl transfer operation to take. Normally,
       name lookups can take a considerable time and  limiting  operations  to
       less than a few minutes risk aborting perfectly normal operations. This
       option may cause libcurl to use the SIGALRM signal  to  timeout  system
       calls.

       In  unix-like  systems, this might cause signals to be used unless CUR-
       LOPT_NOSIGNAL(3) is set.

       If both CURLOPT_TIMEOUT(3) and CURLOPT_TIMEOUT_MS(3) are set, the value
       set last will be used.

       Since  this puts a hard limit for how long time a request is allowed to
       take, it has limited use in dynamic use  cases  with  varying  transfer
       times. You are then advised to explore CURLOPT_LOW_SPEED_LIMIT(3), CUR-
       LOPT_LOW_SPEED_TIME(3) or using CURLOPT_PROGRESSFUNCTION(3)  to  imple-
       ment your own timeout logic.

DEFAULT
       Default  timeout  is  0  (zero)  which  means it never times out during
       transfer.

PROTOCOLS
       All

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

         /* complete within 20 seconds */
         curl_easy_setopt(curl, CURLOPT_TIMEOUT, 20L);

         curl_easy_perform(curl);
       }

AVAILABILITY
       Always

RETURN VALUE
       Returns CURLE_OK
