NAME

       CURLOPT_TIMEOUT - maximum time the transfer is allowed to complete

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 seconds that you allow
       the libcurl transfer operation to take. Normally, name lookups  can  take  a  considerable
       time  and  limiting  operations 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  CURLOPT_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 option puts a hard limit on how long time a request is allowed to take, it  has
       limited  use in dynamic use cases with varying transfer times. That is especially apparent
       when using the multi interface, which may queue the transfer, and that time  is  included.
       You  are advised to explore CURLOPT_LOW_SPEED_LIMIT(3), CURLOPT_LOW_SPEED_TIME(3) or using
       CURLOPT_PROGRESSFUNCTION(3) to implement 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, "https://example.com");

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

         curl_easy_perform(curl);
       }

AVAILABILITY

       Always

RETURN VALUE

       Returns CURLE_OK. Returns CURLE_BAD_FUNCTION_ARGUMENT if set to  a  negative  value  or  a
       value that when converted to milliseconds is too large.
