// 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 <f32file.h>

// 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.
