// Module Name:
|
|
// Barf.h
|
|
//
|
|
// Abstract:
|
|
// Definition of the Basic Artifical Resource Failure classes.
|
|
// BARF allows API call failures to be simulated automatically to
|
|
// ensure full code test coverage.
|
|
//
|
|
// Implementation File:
|
|
// Barf.cpp
|
|

// Author:

|
|
//
|
|
// Revision History:
|
|
//
|
|
// Notes:
|
|
// This file compiles only in _DEBUG mode.
|
|
//
|
|
// To implement a new BARF type, declare a global instance of CBarf:
|
|
// CBarf g_barfMyApi(_T("My API"));
|
|
//
|
|
// To bring up the BARF dialog:
|
|
// DoBarfDialog();
|
|
// This brings up a modeless dialog with the BARF settings.
|
|
//
|
|
// A few functions are provided for special circumstances.
|
|
// Usage of these should be fairly limited:
|
|
// BarfAll(void); Top Secret -> NYI.
|
|
// EnableBarf(BOOL); Allows you to disable/reenable BARF.
|
|
// FailOnNextBarf; Force the next failable call to fail.
|
|
//
|
|
// NOTE: Your code calls the standard APIs (e.g. LoadIcon) and the
|
|
// BARF files do the rest.

|
|
// Purpose:
|
|
// Basic Artificial Resource Failure class. Contains the BARF
|
|
// information for a class of calls
|
|
//
|
|
// The constructor initializes a bunch of parameters. CBarfDialog
|
|
// (a friend class) adjusts the various flags. The only public API
|
|
// is FFail(). This method determines if the next call should generate
|
|
// an artificial failure or not.

// Temporarily suspends BARF counters. This is especially useful

|
|
//
|
|
// For example:
|
|
//
|

// void Foo(void)

// {

|
// DoFuncA(); // BARF counters are enabled
|
|
//
