No |
Called by a driver to communicate with an interrupt handler. |
|
Yes |
Maps the specified executable module into the address space of the calling process. |
|
Yes |
Locks into memory the specified region of the virtual address space of the process, ensuring that subsequent access to the region does not incur a page fault. |
|
Yes |
Validates whether a region of memory pointed to by the ptr parameter is valid with respect to the caller process. This function is obsolete in Windows Embedded CE. |
|
Yes |
Maps an unmapped pointer to a process. This function is obsolete in Windows Embedded CE. |
|
Yes |
Opens an existing watchdog timer. |
|
Yes |
Swaps out all the pages of a process or DLL that are available for paging. |
|
Yes |
Queries the OEM profiler after it is running. |
|
Yes |
Implemented in the kernel and called by the profiler ISR to record a profiling sample. |
|
Yes |
Implemented in the kernel and called by OEM adapatation layer (OAL) code generating interrupts. ProfilerHitEx is called by the profiler ISR to record a profiling sample. |
|
No |
Starts the Windows Embedded CE instrumented kernel or Monte Carlo profiling. |
|
No |
Starts the profiler. |
|
No |
Stops the Windows Embedded CE instrumented kernel or Monte Carlo profiling and displays a profile report on a debug terminal. |
|
Yes |
Refreshes a watchdog timer. |
|
Yes |
Sets or queries zones for either a process or a module, but not both. |
|
No |
Associates data with an event handle. |
|
Yes |
Used by a device driver to cause an artificial interrupt event. |
|
Yes |
Changes the default Just-in-Time (JIT) debugger dynamically. SetJITDebuggerPath can be called only by a privileged or trusted process. |
|
Yes |
This function is obsolete. |
|
Yes |
Switches between kernel and user modes. This function is obsolete in Windows Embedded CE. |
|
Yes |
Sets the internal permissions bit mask for the current thread, thereby enabling access to the address space of another process. This function is obsolete in Windows Embedded CE. |
|
Yes |
Sets the standard input, output, or error output destination path. |
|
Yes |
Obtains a 1-MB–aligned physical page and returns a pointer to the store queue. |
|
Yes |
Sets the specified number of pages for the object store. This function is obsolete. |
|
No |
Suspends the current thread until the next system tick. |
|
No |
Starts a watchdog timer. |
|
No |
Stops a watchdog timer. |
|
No |
Converts system time to file time format. |
|
Yes |
Deregisters an ISR with a specific hardware interrupt. |
|
Yes |
Unlocks a specified range of pages in the virtual address space of a process, enabling the system to swap the pages out if necessary. |
|
Yes |
Unmaps a memory pointer that was previously mapped using MapPtrToProcess. This function is obsolete in Windows Embedded CE. |
|
Yes |
Binds a specific physical memory range to a statically mapped virtual address. |
|
Yes |

The following table shows additional kernel functions specific to Windows Embedded CE.
| Function | Kernel mode only | Description |
|---|---|---|
No |
Indicates whether the specified API set has been registered. This is a non-polling version of the IsAPIReady function. |
The following table shows new kernel functions specific to Windows Embedded CE 6.0.
| Function | Kernel mode only | Description |
|---|---|---|
No |
Enables drivers to forward I/O controls to other drivers when the driver does not know anything about the I/O control so that no validation is performed. The driver that is called into still has the correct direct caller information to perform parameter validation. |
|
No |
Obtains the process identifier of the caller that originated the call to the API. |
|
No |
Obtains the direct caller's process identifier. |
Remarks
In Windows Embedded CE 6.0, kernel mode means running inside the kernel as a kernel thread. Before CE 6.0, kernel mode essentially meant that you called SetKMode.
