|
|
.SH NAME
|
|
CURLOPT_NOSIGNAL \- skip all signal handling
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOSIGNAL, long onoff);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
If \fIonoff\fP is 1, libcurl uses no 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 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.
