/**

@file test_udf_services.cc

This is a test suite plugin to verify that plugins can co-exist with UDFs.
|
|
The file defines one DAEMON plugin @ref test_udf_services_plugin and one
|
|
UDF function: @ref test_udf_services_udf.
|
|
The test then checks if the plugin can be unloaded and loaded while the
|
|
UDF is defined.
|
|
|
|
No user-facing functionality in this plugin. Just test material !
