|
.SH NAME
|
|
CURLOPT_CONNECTTIMEOUT \- timeout for the connect phase
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONNECTTIMEOUT, long timeout);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a long. It sets the maximum time in seconds that you allow the connection
|
|
phase to take. This timeout only limits the connection phase, it has no impact
|
|
once libcurl has connected. The connection phase includes the name resolve
|
|
(DNS) and all protocol handshakes and negotiations until there is an
|
|
established connection with the remote side.
|
|
|
|
Set this option to zero to switch to the default built\-in connection timeout \-
|
|
300 seconds. See also the \fICURLOPT_TIMEOUT(3)\fP option.
|
|
|
|
\fICURLOPT_CONNECTTIMEOUT_MS(3)\fP is the same function but set in milliseconds.
|
|
|
|
If both \fICURLOPT_CONNECTTIMEOUT(3)\fP and \fICURLOPT_CONNECTTIMEOUT_MS(3)\fP
|
|
are set, the value set last is used.
|
|
|
|
The connection timeout is included in the general all\-covering
|
|
\fICURLOPT_TIMEOUT(3)\fP:
|
|
|
|
With \fICURLOPT_CONNECTTIMEOUT(3)\fP set to 3 and \fICURLOPT_TIMEOUT(3)\fP set
|
|
to 5, the operation can never last longer than 5 seconds, and the connection
|
|
phase cannot last longer than 3 seconds.
|
|
|
|
With \fICURLOPT_CONNECTTIMEOUT(3)\fP set to 4 and \fICURLOPT_TIMEOUT(3)\fP set
|
|
to 2, the operation can never last longer than 2 seconds. Including the
|
|
connection phase.
|
|
|
|
This option may cause libcurl to use the SIGALRM signal to timeout system
|
|
calls on builds not using asynch DNS. In unix\-like systems, this might cause
|
|
signals to be used unless \fICURLOPT_NOSIGNAL(3)\fP is set.
|
|
.SH DEFAULT
|
|
300
|
|
