Create a new session

Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Session_Create function is the SetSession subroutine.

$Session_Create creates a new session, and it returns a zero, indicating success, or a number indicating the cause of error, if there is one.

Syntax

%rc = $Session_Create(sesid, [owner], [timeout], [opts])

sesid The ID to be given to the new session. This is a required argument.
owner The userid that will own this session. An owner value of asterisk (*) means that the session is public, that is available to all users. Only a system administrator can create a non-public session for a user other than itself. This optional argument defaults to the creating user's userid.
timeout The time after a $Session_Close (or logout) after which the session is considered timed-out, that is, eligible for deletion. A value of -1 means use the SESDEFTO parameter value. This optional argument defaults to -1, that is the SESDEFTO parameter value.
opts A blank-delimited set of options to control the create process. The options are:
OPEN Automatically open the session upon creating it. This is the default behavior.
NOOPEN Don't automatically open the session upon creating it. This is not the default behavior but might be useful if creating a session for another user or creating many sessions at once.

Return codes

%rc is set to 0 or to an error indicator.

0 - No errors 1 - Session id already exists for user 2 - Online session limit exceeded 3 - User session limit exceeded

Example

The following example creates a session called GROUCHO, followed by a timestamp then sets a cookie for a web application so that the session can be easily located on subsequent web requests.

%sesid = 'GROUCHO' WITH $SirTime %rc = $Session_Create(%sesid, , 3600) %rc = $Web_Set_Cookie('SESID', %sesid)
