.TH CURLOPT_NOSIGNAL 3 "16 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_NOSIGNAL \- skip all signal handling
|
||
|
|
.SH SYNOPSIS
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NOSIGNAL, long onoff);
|
||
|
|
.SH DESCRIPTION
|
||
|
|
If \fIonoff\fP 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. The default value for
|
||
|
|
this parameter is 0.
|
||
|
|
|
||
|
|
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 \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 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
|
||
|
|
\fICURLAUTH_NTLM_WB\fP authentication could cause a SIGCHLD signal to be
|
||
|
|
raised.
