Parameter Description Example
curl The CURL session handle. $curl
Value The connection timeout time in milliseconds. 300000


Returns "OK" on success.


Sets the connection timeout in milliseconds.
Like CURL.SetOptionConnectionTimeout but takes the number of milliseconds instead. If libcurl is built to use the standard system name resolver, that portion of the connect will still use full-second resolution for timeouts with a minimum timeout allowed of one second.

See also CONNECTTIMEOUT_MS option in CURL manual.

Set Variable [ $r; Value: MBS( "CURL.SetDebugWithTime"; $curl; 1 )
Set Variable [ $r; Value: MBS( "CURL.SetDebugWithProgress"; $curl; 1 )
# and define some timeouts
Set Variable [ $r; Value: MBS( "CURL.SetOptionConnectTimeoutMS"; $curl; 10000 )
