NAME
     csa_delete_entry - delete an entry from a calendar

SYNOPSIS
     #include <csa.h>
     CSA_return_code csa_delete_entry(CSA_session_handle session,
                                      CSA_entry_handle entry,
                                      CSA_enum delete_scope,
                                      CSA_extension *delete_entry_extensions);

DESCRIPTION
     The csa_delete_entry() function will delete an  entry  in  a
     calendar.  The delete_scope indicates the scope of the dele-
     tion if the entry has any associated recurring entries.  All
     of  the recurring entries can be deleted, only the specified
     entry can be deleted, or only  the  recurring  entries  that
     follow  the specified entry can be deleted.  Only the calen-
     dar  owner,  users   with   CSA_OWNER_RIGHTS,   users   with
     CSA_UPDATE_PUBLIC_ENTRIES,             users            with
     CSA_UPDATE_CONFIDENTIAL_ENTRIES,     or      users      with
     CSA_UPDATE_PRIVATE_ENTRIES  access rights can delete entries
     on the 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.

  Entry (Entry Handle)
     The handle of the calendar entry  to  be  deleted.   If  the
     entry     handle     is     invalid,    then    the    error
     CSA_E_INVALID_ENTRY_HANDLE is returned.

  Delete Scope (Enum)
     The scope  for  the  delete  operation.   Operator  settings
     include:

        CSA_SCOPE_ALL
              If set and the entry is associated  with  recurring
              entries,  it  specifies  that  all of the recurring
              entries are to be deleted.

        CSA_SCOPE_ONE
              If set and the entry is associated  with  recurring
              entries, it specifies that only the specified entry
              is to be deleted.

        CSA_SCOPE_FORWARD
              If set and the entry is associated  with  recurring
              entries,  it  specifies  that  only  the  recurring
              entries following the specified  entry  are  to  be
              deleted.   The  scope  also  includes the specified
              entry.

  Delete Entry 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 informa-
     tion.

RETURN VALUE
  Delete Entry Extensions (Extension)
     If output extensions were passed  to  the  function  in  the
     extensions list, the results from the service will be avail-
     able 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.
