(PHP 4 >= 4.0.5, PHP 5 <= 5.0.4)
udm_free_ispell_data() always returns TRUE.
agent - agent link identifier, received after call to udm_alloc_agent().
Замечание: This function is supported beginning from version 3.1.12 of mnoGoSearch and it does not do anything in previous versions.
in mnogosearch 3.2.33 (and earlier 3.2.x versions) this function should not be used, as udm_free_agent() implicitly frees this memory too. as a result, you will have "double free" and crash of php/apache instance
