NAMEcsa_logon — log on to the calendar service and establish a session with
a calendar
SYNOPSIS
#include <xcsa.h>
CSA_return_code csa_logon(
CSA_service_reference calendar_service,
CSA_calendar_user *user,
CSA_string password,
CSA_string character_set,
CSA_string required_csa_version,
CSA_session_handle *session,
CSA_extension *logon_extensions);
DESCRIPTION
The csa_logon function allows the calling application to logon to the
calendar service. If the specified calendar does not exist, then the
error CSA_E_CALENDAR_NOT_EXIST is returned.
The function returns a Session Handle that the application will use in
subsequent CSA calls.
ARGUMENTS
Calendar Service (Service Reference)
A calendar service name specifying the requested calendaring service,
(e.g., the path to a calendar store or a remote server node name).
This value may be NULL if the underlying calendaring service does not
require a service name or if UI is allowed. This may be necessary on
some implementations and ignored on others.
User (Calendar User)
A pointer to the calendar user structure that identifies the user and
calendar to the calendaring service. This value may be NULL.
Password (String)
A string containing the password required for access to the CSA ser‐
vice. This value may be NULL if the underlying calendaring service
does not require a password or if UI is allowed.
Character Set (String)
A CSA formal public identifier string for the character set of strings
used by the CSA caller. The client may pass NULL in which case the
character set used is determined by the CSA service. The supported
values are implementation specific.
Required CSA Version (String)
The formal public identifier for the CSA version number required by the
application. For this version of the specification this string must be
``-//XAPIA/CSA/VERSION1/NONSGML CSA Version 1//EN''.
Logon Extensions (Extensions)
A pointer to an array of CSA_extension structures for this function.
The array may contain both input extensions for providing additional
information to the function and output extensions for receiving infor‐
mation from the function. A value of NULL indicates that the caller is
not using any extensions. See the extensions structure for more infor‐
mation.
Through extensions, the application can find out which extensions are
available and set which data extensions will be active for the session.
RETURN VALUE
Session (Session Handle)
Opaque session handle that represents a session with the CSA calendar.
Logon Extensions (Extensions)
If output extensions were passed to the function in the extensions
list, the results from the service will be available in the extension.
See the extensions structure for more information. Whether the func‐
tion succeeded or not, and, if not, why. It may be success or one of
the values listed under ERRORS below.
