sl@0: // Overview:
sl@0: // Tests failure codes when loading a RProcess or RLibrary.
sl@0: // Introduced as test for defect DEF092502
sl@0: // API Information:
sl@0: // RProcess, RLibrary
sl@0: // Details:
sl@0: // - Test attempting to open a non-existent DLL fails gracefully
sl@0: // - Test attempting to open a DLL of an invalid name fails gracefully
sl@0: // - Test attempting to open a non-existent EXE fails gracefully
sl@0: // - Test attempting to open an EXE of an invalid name fails gracefully
sl@0: // - Test loading a dll with an incorrect version number as part of it name
sl@0: // will return KErrCorupt
sl@0: // Platforms/Drives/Compatibility:
sl@0: // All
sl@0: // Assumptions/Requirement/Pre-requisites:
sl@0: // Assumes drive 'z' always contains \img\t_ver1{00010001}.dll
sl@0: // Assumes drive 'c' is writeable
sl@0: // Failures and causes:
sl@0: // Base Port information:
sl@0: // Error codes returned on h/w and emulator should be the same
sl@0: // 
sl@0: //
