NAME
csa_read_calendar_attributes — read and return the calendar attributes values for a calendar

SYNOPSIS

#include <xcsa.h>
CSA_return_code csa_read_calendar_attributes(
CSA_session_handle session,
CSA_uint32 number_names,
CSA_attribute_reference *attribute_names,
CSA_uint32 *number_attributes,
CSA_attribute **calendar_attributes,
CSA_extension *read_calendar_attributes_extensions);

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 csa_free(3).

  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. It may be success or one of the values listed under ERRORS below.
