** 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
**
