| GwesPowerOffSystem | This function initiates a power–down or suspend state. It is called by an OEM. |
| InitPubKey | This function initializes a public key to be used for signature verification. |
| KLocalFileTimeToFileTime | This function converts a local file time to a file time based on the Universal Time Coordinate (UTC). |
| LoadKernelLibrary | This function loads a DLL into the kernel's address space. |
| lpReadDebugByteFunc | This function points to the OEMReadDebugByte function by default. It is defined in the kernel. |
| lpWriteDebugByteFunc | This function points to the OEMWriteDebugByte function by default. It is defined in the kernel. |
| lpWriteDebugStringFunc | This function points to the OEMWriteDebugString function by default. It is defined in the kernel. |
| NKIsSysIntrValid | This function determines if a particular interrupt identifier, or SYSINTR, value is valid |
| NKrdmsr | This function puts the CPU into ring 0, if it is not already there. It is a C wrapper function for the x86 RDMSR instruction. |
| NKRegCreateKeyEx | This function creates a specified key. If the key already exists in the registry, the function opens it. |
| NKRegCloseKey | This function releases the handle of the specified key. |
| NKRegOpenKeyEx | This function opens the specified key. |
| NKRegQueryValueEx | This function retrieves the type and data for a specified value name associated with an open registry key. |
| NKRegSetValueEx | This function stores data in the value field of an open registry key. It can also set additional value and type information for the specified key. |
| NKSetDataAbortHandler | This function replaces the default abort handler on an ARM built OS. It is used by OEMs. |
| NKVirtualSetAttributes | This function changes the per-page attributes for a range of virtual memory, which is usually copied from a physical location not known to the kernel. It is used by driver developers. |
| NKwrmsr | This function puts the CPU into ring 0, if it is not already there. It is a C wrapper function for the x86 WRMSR instruction. |
| NotifyWinUserSystem | This function notifies the system that a system setting was changed. |
| PFN_AllocHeapMem | This function allocates heaps. It is a custom function. |
| PFN_EnumProc | This function enumerates a device name.. |
| PFN_FreeHeapMem | This function deallocates heaps. It is a custom function. |
| PFN_KITLTIMERCB | This function is called when a KitlSetTimerCallback registered timer expires. |
| PowerOffSystem | This function calls the kernel to do the final power–down steps before suspending the device. |
| SetCleanRebootFlag | This function resets the object store when a device resets. |
| SetOOMEvent | This function enables enhanced memory management features of Windows CE. |
| VirtualSetPageFlags | This function maps the VSPF_* flags to SH4 virtual page attribute flags and sets the flags for all the pages in the range specified by the lpvAddres and cbSize parameters. |
