wiautil.h contains the following programming interfaces:
Classes
| CWiauDbgFn The CWiauDbgFn class is a helper class that is used for tracing function or method entry and exit points. |
| CWiauFormatConverter The CWiauFormatConverter class is a helper class for converting images to BMP format. |

Functions
| WIAS_ASSERT Learn how the WIAS_ASSERT macro writes a diagnostic message to the Wiatrace.log file. |
| WIAS_ERROR Learn how the WIAS_ERROR macro writes a diagnostic message to the Wiatrace.log file. |
| WIAS_HRESULT Learn how the WIAS_HRESULT macro writes a diagnostic message to the Wiatrace.log file. |
| WIAS_LERROR The WIAS_LERROR macro is obsolete for Windows Vista and later. It is recommended that the WIAS_ERROR macro be used instead.The WIAS_LERROR macro writes a diagnostic WIA_ERROR message to the log file. |
| WIAS_LHRESULT The WIAS_LHRESULT macro is obsolete for Windows Vista and later. It is recommended that the WIAS_HRESULT macro be used instead. The WIAS_LHRESULT macro translates an HRESULT value into a string and writes the string to the diagnostic log file. |
| WIAS_LTRACE The WIAS_LTRACE macro is obsolete for Windows Vista and later. It is recommended that the WIAS_TRACE macro be used instead.The WIAS_LTRACE macro writes a diagnostic WIA_TRACE message to the log file. |
| WIAS_LWARNING The WIAS_LWARNING macro is obsolete for Windows Vista and later.The WIAS_LWARNING macro writes a diagnostic WIA_WARNING message to the log file. |
| WIAS_TRACE Learn how the WIAS_TRACE macro writes a diagnostic message to the Wiatrace.log file. |
| wiauDbgDump The wiauDbgDump function logs a message containing one or more data values. |
| wiauDbgError The wiauDbgError function logs an error message. |
| wiauDbgErrorHr The wiauDbgErrorHr function logs a message containing an HRESULT and its error message string. |
| wiauDbgFlags The wiauDbgFlags function determines whether a particular debugging flag is set. |
| wiauDbgHelper The wiauDbgHelper function formats a message and writes it to a log file, or debugger, or both. |
| wiauDbgHelper2 The wiauDbgHelper2 function writes a message to a log file, or debugger, or both. |
| wiauDbgInit The wiauDbgInit function initializes WIA debugging. |
| wiauDbgLegacyError The wiauDbgLegacyError function logs an error message. |
| wiauDbgLegacyError2 The wiauDbgLegacyError2 function logs an error message. |
| wiauDbgLegacyHresult2 The wiauDbgLegacyHresult2 function logs a default message containing an HRESULT. |
| wiauDbgLegacyTrace The wiauDbgLegacyTrace function logs a trace message. |
| wiauDbgLegacyTrace2 The wiauDbgLegacyTrace2 function logs a trace message. |
| wiauDbgLegacyWarning The wiauDbgLegacyWarning function logs a warning message. |
| wiauDbgSetFlags The wiauDbgSetFlags function sets debugging flags. |
| wiauDbgTrace The wiauDbgTrace function logs a trace message. |
| wiauDbgWarning The wiauDbgWarning function logs a warning message. |
| wiauGetDrvItemContext The wiauGetDrvItemContext function gets the driver item context, and optionally, the driver item. |
| wiauGetResourceString The wiauGetResourceString function gets a resource string, storing it as a BSTR. |
| wiauGetValidFormats The wiauGetValidFormats function calls the IWiaMiniDrv::drvGetWiaFormatInfo method and makes a list of valid formats, using a specified tymed value. |
| wiauPropInPropSpec The wiauPropInPropSpec function determines whether a specified property specification ID is contained in an array of such values. The function optionally gets the index at which the property specification ID was found. |
| wiauPropsInPropSpec The wiauPropsInPropSpec function determines whether any of a list of property specification IDs is contained within an array of such values. |
| wiauRegGetDwordA The wiauRegGetDword function gets a DWORD value from the DeviceData section of the registry. |
| wiauRegGetDwordW Learn how the wiauRegGetDword function gets a DWORD value from the DeviceData section of the registry. |
| wiauRegGetStrA The wiauRegGetStr function gets a string value from the DeviceData section of the registry. |
| wiauRegGetStrW Learn how the wiauRegGetStr function gets a string value from the DeviceData section of the registry. |
| wiauRegOpenDataA The wiauRegOpenData function opens the DeviceData registry key. |
| wiauRegOpenDataW Learn how the wiauRegOpenData function opens the DeviceData registry key. |
| wiauSetImageItemSize The wiauSetImageItemSize function calculates the size and width, in bytes, for an image, based on the current WIA_IPA_FORMAT setting (described in the Microsoft Windows SDK documentation), and writes the new values to the appropriate properties. |
| wiauStrC2C The wiauStrC2C function copies an ANSI character string to another ANSI character string. |
| wiauStrC2W The wiauStrC2W function converts an ANSI character string to a Unicode string. |
| wiauStrW2C The wiauStrW2C function converts a Unicode string to an ANSI character string. |
| wiauStrW2W The wiauStrW2W function copies a Unicode string to another Unicode string. |
Structures
