DESCRIPTION
The
csa_read_calendar_attributes function returns an array of attributes structures
containing the values of the calendar attributes of the
specified calendar.
The function will return all of the
attributes if
number_names argument is zero and
attribute_names argument is
NULL. Only the owner of the calendar, users with
CSA_OWNER_RIGHTS, or users with
CSA_VIEW_CALENDAR_ATTRIBUTES access rights can read the calendar atttributes.
ARGUMENTS
Session (Session Handle)
Opaque session handle that represents a session with the
calendaring service.
Session handles are created by a logon function call and
invalidated with a logoff function call.
If the session
handle is invalid, then the error
CSA_E_INVALID_SESSION_HANDLE is returned.
Number Names (Uint32)
The number of calendar attribute names in
attribute_names. If zero, then all of the attributes will be returned.
If
the
attribute_names argument is
NULL, then this must be zero.
Attribute Names (Attribute Names)
A pointer to an array of attribute names that are to be
read.
If
NULL, then all of the attributes will be returned.
If the
number_names argument is zero, then this must be
NULL.
Read Calendar Attributes Extensions (Extension)
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
information from the function.
A value of
NULL indicates that the caller is not using any extensions.
See the extensions structure for more information.
RETURN VALUE
Number Attributes (Uint32)
A pointer to the number of attributes returned in
calendar_attributes.
The error
CSA_E_INSUFFICIENT_MEMORY is returned if there is the service has insufficient memory
to store the complete set of requested information.
Calendar Attributes (Attribute)
A pointer to an array of attribute structures containing
the values for the calendar attributes for the specified
calendar.
This array is allocated by the service, and
should be freed with a single call to
&cdeman.csa.free;.
Read Calendar Attributes Extensions (Extension)
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 function succeeded or
not, and, if not, why.
