csa_free_time_search(3)
CDE
NAME
csa_free_time_search - searches one or more calendars for available free
time
SYNOPSIS
#include <xcsa.h>
CSA_return_code csa_free_time_search(CSA_session_handle session,
CSA_date_time_range date_time_range,
CSA_time_duration time_duration,
CSA_uint32 number_users,
CSA_calendar_user *calendar_users,
CSA_free_time **free_time,
CSA_extension
*free_time_search_extensions);
DESCRIPTION
The csa_free_time_search function searches for available free time on one
or more calendars and returns a list of free time intervals found. Free
time is an interval of time that is not currently scheduled on one or more
calendars. The free time search is based on a date and time range and the
minimum time duration required of the free time interval. Only the owner of
the calendar, users with CSA_FREE_TIME_SEARCH, users with
CSA_VIEW_PUBLIC_ENTRIES, users with CSA_VIEW_CONFIDENTIAL_ENTRIES, or users
with CSA_VIEW_PRIVATE_ENTRIES can search the calendar for free time.
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.
Date Time Range (Date Time Range)
Specifies the start and stop date and time range for the free time search.
If the date_time_range is invalid, then the error CSA_E_INVALID_DATE_TIME
is returned.
Time Duration (Time Duration)
Specifies the minimum time range for the free time intervals to be sought.
If the time duration is invalid, then the error CSA_E_INVALID_DATE_TIME is
returned.
Number Users (Uint32)
The number of elements in the calendar_users argument.
Calendar Users (Calendar User)
A pointer to an array of calendar users. This specifies the calendars to be
searched for available free time. If the user does not have authority to
access any of the attendee's calendars, then the error CSA_E_NO_AUTHORITY
is returned. If an invalid attendee is specified, then the error
CSA_E_INVALID_USER is returned. It is implementation specific whether the
seach function will proceed in any of these cases.
Free Time Search 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
Free Time (Free Time)
A pointer to a free time structure that specifies a set of free time
intervals.
If more free time intervals are found than can be represented in the
available memory, the CSA_E_INSUFFICIENT_MEMORY error message will be
returned. If no available free time is found, then a NULL pointer will be
returned. This structure is allocated by the service, and should be freed
with a single call to csa_free(3).
Free Time Search 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.
