// Dirent_Test.cpp
//
// = DESCRIPTION
// This is a test of the opendir and readdir emulation provided by the
// class ACE_OS_Dirent. It is used to ensure that the emulation code
// works properly on platforms that don't support this capability
// natively. As the emulation code is not compiled in other
// platforms, this test also ensures that there is no impact to
// platforms that natively support directory scanning operations.
