The following table lists the miscellaneous GDI utility services. These services include debugging support, getting and setting the last error, several conversion services that convert from one character encoding type to another, a sort routine, and others.

Function	Description
EngBugCheckEx	Brings down the system in a controlled manner when the caller discovers an unrecoverable inconsistency.
EngDebugBreak	Causes a breakpoint in the current process to occur.
EngDebugPrint	Prints the specified debug message to the kernel debugger.

EngMultiByteToWideChar	Converts an ANSI source string into a wide character string using the specified code page.
EngProbeForRead	Probes a structure for read accessibility.
EngProbeForReadAndWrite	Probes a structure for read and write accessibility.
EngSetLastError	Causes GDI to report an error code, which can be retrieved by an application.
EngSort	Performs a quick-sort on the specified list.
EngUnicodeToMultiByteN	Converts the specified Unicode string into an ANSI string using the current ANSI code page.
EngWideCharToMultiByte	Converts a wide character string into an ANSI source string using the specified code page.
