curlopt_nosignal
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 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
AVAILABILITY
Added in 7.10
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
