SYNOPSIS

#include &<xcsa.h>
CSA_return_code csa_read_next_reminder(
CSA_session_handle session,
CSA_uint32 number_names,

CSA_uint32 *number_reminders,
CSA_reminder_reference **reminder_references,
CSA_extension *read_next_reminder_extensions);

DESCRIPTION

The csa_read_next_reminder function reads the next reminder of the specified type in the specified calendar relative to a given time. More than one type of reminder may be specified. For each reminder type specified, the next reminder of that type after the given time will be returned. The owner of the calendar or users with CSA_OWNER_RIGHTS access right can read the next reminder for a calendar.

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)

Specifies the size of reminder_names.

Reminder Names (Attribute Reference)

A pointer to an array of attribute references. This is an array of reminder attribute names. The names are used as search criteria to return the next reminder of each type. If NULL, then the first reminder after the given time will be returned, no matter what type it is. If an invalid reminder type is specified, then the error CSA_E_INVALID_ATTRIBUTE is returned.

Given Time (Date Time)

The given date and time after which the search for the next reminder is to begin. If the date and time value is incorrect, then the error CSA_E_INVALID_DATE_TIME will be returned.

RETURN VALUE

Number Reminders (Uint32)

The number of reminder reference structures returned in reminder_references. If no reminders were found a value of zero is returned.

Reminder References (Reminder Reference)

A pointer to an array of reminder reference structures. This array is allocated by the service, and should be freed with a single call to csa_free(3).
