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 resolves 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 SIGPIPEs 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,
       contrary to our desire. In addition, using CURLAUTH_NTLM_WB authentication could cause a  SIGCHLD  signal
       to be raised.

DEFAULT

       0

RETURN VALUE

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