NAMEcsa_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 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.
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 repre‐
sented 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 ser‐
vice, 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 func‐
tion succeeded or not, and, if not, why. It may be success or one of
the values listed under ERRORS below.
