+/*=====================================================================
+**
+** Source: test1.c (fdopen)
+**
+** Purpose: Tests the PAL implementation of the fdopen function.
+** This will test fdopen in r (read) mode. This test
+** creates and opens a test pipe, to write and read
+** from. fdopen requires a file handle(int), therefore
+** _open_osfhandle is used to get that handle.
+** _open_osfhandle is only used with CreatePipe. The
+** test will write and read from the pipe comparing
+** the results.
+**
+** See /tests/palsuite/README.txt for more information.
