+** Source:  test2.c (_open_osfhandle)
+**
+** Purpose: Tests the PAL implementation of the _open_osfhandle function.
+**          This API accepts a OS Handle returned from CreatePipe() and
+**          a flag of _O_RDONLY and returns a C Run-Time handle. The test
+**          will pass a NULL handle, and unsupported flags. All cases
+**          should fail.
+**
+** Depends: CreatePipe
+**          CloseHandle
+**
