+// Description:
+// e32test\dll\t_loadfail.cpp
+// Overview:
+// Tests failure codes when loading a RProcess or RLibrary.
+// Introduced as test for defect DEF092502
+// API Information:
+// RProcess, RLibrary
+// Details:
+// - Test attempting to open a non-existent DLL fails gracefully
+// - Test attempting to open a DLL of an invalid name fails gracefully
+// - Test attempting to open a non-existent EXE fails gracefully
+// - Test attempting to open an EXE of an invalid name fails gracefully
+// - Test loading a dll with an incorrect version number as part of it name
+// will return KErrCorupt
+// Platforms/Drives/Compatibility:
+// All
+// Assumptions/Requirement/Pre-requisites:
+// Assumes drive 'z' always contains \img\t_ver1{00010001}.dll
+// Assumes drive 'c' is writeable
+// Failures and causes:
+// Base Port information:
+// Error codes returned on h/w and emulator should be the same
+// 
+//
+
+#include <e32test.h>
+#include <f32file.h>

+RTest test(_L("T_LOADFAIL"));
+
+// Test loading dll with incorrect version number in the name returns KErrCorrupt
+// as the loader will compare the image header version number against that in the
+// image file's name
+LOCAL_D TInt TestVersionL()
+	{
+// Test only valid on target h/w as emulator uses MS Windows loader which doesn't allow verison 
+// no. to be in part of the dll name.
