CURLOPT_NOSIGNAL(3)

CURLOPT_NOSIGNAL(3)        curl_easy_setopt options        CURLOPT_NOSIGNAL(3)

NAME
       CURLOPT_NOSIGNAL - skip all signal handling

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOSIGNAL, long onoff);

DESCRIPTION
       If  onoff  is 1, libcurl will not use any functions that install signal
       handlers or any functions that cause signals to be sent to the process.
       This option is here to allow multi-threaded unix applications to  still
       set/use all timeout options etc, without risking getting signals.

       If this option is set and libcurl has been built with the standard name
       resolver,  timeouts  will not occur while the name resolve takes place.
       Consider building libcurl with the c-ares or threaded resolver backends
       to enable asynchronous DNS lookups, to enable  timeouts  for  name  re‐
       solves without the use of signals.

       Setting  CURLOPT_NOSIGNAL(3)  to  1 makes libcurl NOT ask the system to
       ignore SIGPIPE signals, which otherwise are sent  by  the  system  when
       trying  to  send  data  to  a  socket which is closed in the other end.
       libcurl makes an effort to never cause such SIGPIPE signals to trigger,
       but some operating systems have no way to avoid them and even on  those
       that  have there are some corner cases when they may still happen, con‐
       trary to our desire. In addition, using CURLAUTH_NTLM_WB authentication
       could cause a SIGCHLD signal to be raised.

DEFAULT
       0

PROTOCOLS
       All

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

         curl_easy_setopt(curl, CURLOPT_NOSIGNAL, 1L);

         ret = curl_easy_perform(curl);

         curl_easy_cleanup(curl);
       }

AVAILABILITY
       Added in 7.10

RETURN VALUE
       Returns CURLE_OK if the option is supported,  and  CURLE_UNKNOWN_OPTION
       if not.
