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 cannot 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 \fICURLOPT_NOSIGNAL(3)\fP 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, contrary to our desire. In addition, -using \fICURLAUTH_NTLM_WB\fP authentication could cause a SIGCHLD signal to be -raised. -.SH DEFAULT -0 -.SH PROTOCOLS -All -.SH EXAMPLE -.nf -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); -} -.fi -.SH AVAILABILITY -Added in 7.10 -.SH RETURN VALUE -Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. -.SH SEE ALSO -.BR CURLOPT_TIMEOUT "(3), " |
