csa_free_time_searUNIX)System V (1 August csa_free_time_search(3)
NAME
csa_free_time_search - searches one or more calendars for
available free time
SYNOPSIS
#include <csa.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
Page 1 (printed 9/3/04)
csa_free_time_searUNIX)System V (1 August csa_free_time_search(3)
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.
