NAME

       CURLOPT_TIMEOUT_MS - maximum time the transfer is allowed to complete

SYNOPSIS

       #include <curl/curl.h>

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

DESCRIPTION

       Pass  a  long  as parameter containing timeout - the maximum time in milliseconds 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.

       If libcurl is built to use the standard system name resolver, that portion of the transfer
       will still use full-second resolution for timeouts with a minimum timeout allowed  of  one
       second.

       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  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),      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 20000 milliseconds */
         curl_easy_setopt(curl, CURLOPT_TIMEOUT_MS, 20000L);

         curl_easy_perform(curl);
       }

AVAILABILITY

RETURN VALUE

       Returns CURLE_OK
