Sets the maximum time in seconds that you allow the transfer operation to take.
Normally, name lookups can take a considerable time and limiting operations to less than a few minutes risk aborting perfectly normal operations. This option will cause curl to use the SIGALRM to enable time-outing system calls.

See also TIMEOUT option in CURL manual.


Sets timeout to one minute:

MBS( "CURL.SetOptionTimeOut"; $curl; 60 )

Try whether google is available:

Let ( [
# new session
curl = MBS("CURL.New");
# only connect, don't transfer data
r = MBS("CURL.SetOptionConnectOnly"; curl; 1);
# limit time to 1 second to connect and 2 seconds in total
r = MBS("CURL.SetOptionConnectionTimeout"; curl; 1);
r = MBS("CURL.SetOptionTimeOut"; curl; 2);
# new connection please
r = MBS("CURL.SetOptionFreshConnect"; curl; 1);
r = MBS("CURL.SetOptionForbidReuse"; curl; 1);
# we query google here
r = MBS("CURL.SetOptionURL"; curl; "");
# and try it!
result = MBS("CURL.Perform"; curl);
# optionally have log messages go there
// $$log = MBS("CURL.GetDebugMessages"; curl);
# and cleanup
r = MBS("CURL.Release"; curl)
]; result )
