<p>The <b>Native API</b> is a lightweight <a href="Application_programming_interface" class="mw-redirect" title="Application programming interface">application programming interface</a> (API) used by <a href="Windows_NT" title="Windows NT">Windows NT</a>'s <a href="Ntoskrnl.exe" title="Ntoskrnl.exe">kernel</a> and <a href="User_mode" class="mw-redirect" title="User mode">user mode</a> applications. This API is used in the early stages of <a href="Windows_NT_startup_process" class="mw-redirect" title="Windows NT startup process">Windows NT startup process</a>, when other components and APIs are still unavailable. Therefore, a few Windows components, such as the <a href="Client/Server_Runtime_Subsystem" title="Client/Server Runtime Subsystem">Client/Server Runtime Subsystem</a> (CSRSS), are implemented using the Native API. The Native API is also used by <a href="Subroutine" class="mw-redirect" title="Subroutine">subroutines</a> such as those in <a href="Kernel32.dll" class="mw-redirect" title="Kernel32.dll">kernel32.dll</a> that implement the <a href="Windows_API" title="Windows API">Windows API</a>, the API based on which most of the Windows components are created.

</p><p>Most of the Native API calls are implemented in <a href="Ntoskrnl.exe" title="Ntoskrnl.exe">ntoskrnl.exe</a> and are exposed to user mode by <b>ntdll.dll</b>. The <a href="Entry_point" title="Entry point">entry point</a> of ntdll.dll is <code>LdrInitializeThunk</code>. Native API calls are handled by the <a href="Windows_NT_kernel" class="mw-redirect" title="Windows NT kernel">kernel</a> via the <a href="System_Service_Descriptor_Table" title="System Service Descriptor Table">System Service Descriptor Table</a> (SSDT).

</p>

<div class="mw-heading mw-heading2"><h2 id="Function_groups">Function groups</h2></div>

<p>The Native API comprises many functions. They include <a href="C_standard_library" title="C standard library">C runtime functions</a> that are needed for a very basic <a href="C_(programming_language)" title="C (programming language)">C</a> runtime execution, such as strlen(), sprintf(), memcpy() and floor(). Other common procedures like malloc(), printf(), scanf() are missing (the first because it does not specify a <a href="Dynamic_memory_allocation" class="mw-redirect" title="Dynamic memory allocation">heap</a> to allocate memory from and the second and third because they use the console, accessed only via KERNEL32.DLL). The vast majority of other Native API routines, by convention, have a 2 or 3 letter prefix, which is:

</p>

<ul><li><b>Nt</b> or <b>Zw</b> are <a href="System_call" title="System call">system calls</a> declared in ntdll.dll and ntoskrnl.exe. When called from ntdll.dll in user mode, these groups are almost exactly the same; they execute an <a href="Interrupt" title="Interrupt">interrupt</a> into <a href="Ring_(computer_security)" class="mw-redirect" title="Ring (computer security)">kernel mode</a> and call the equivalent function in ntoskrnl.exe via the <a href="System_Service_Dispatch_Table" class="mw-redirect" title="System Service Dispatch Table">SSDT</a>. When calling the functions directly in ntoskrnl.exe (only possible in kernel mode), the Zw variants ensure kernel mode, whereas the Nt variants do not.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> The Zw prefix does not stand for anything.<sup id="cite_ref-oldnewthing_2-0" class="reference"><a href="#cite_note-oldnewthing-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup></li>

<li><b>Rtl</b> is the second largest group of ntdll calls. These comprise the (extended) C Run-Time Library, which includes many utility functions that can be used by native applications, yet don't directly involve kernel support.</li>

<li><b>Csr</b> are client-server functions that are used to communicate with the Win32 subsystem process, <a href="Csrss.exe" class="mw-redirect" title="Csrss.exe">csrss.exe</a> (<i>csrss</i> stands for client/server runtime sub-system).</li>

<li><b>Dbg</b> are <a href="Debugging" title="Debugging">debugging</a> functions such as a software <a href="Breakpoint" title="Breakpoint">breakpoint</a>.</li>

<li><b>Ki</b> are upcalls from kernel mode for events like <a href="Asynchronous_procedure_call" title="Asynchronous procedure call">APC</a> dispatching.</li>

<li><b>Ldr</b> are loader functions for <a href="Portable_Executable" title="Portable Executable">PE</a> file handling and starting of new processes.</li>

<li><b>Nls</b> for <a href="Internationalization_and_localization" title="Internationalization and localization">National Language Support</a> (similar to code pages).</li>

<li><b>Pfx</b> for prefix handling.</li>

<li><b>Tp</b> for threadpool handling.</li></ul>

<p>user32.dll and gdi32.dll include several other calls that execute an interrupt into kernel mode. These were not part of the original Windows NT design, as can be seen in <a href="Windows_NT_3.5" title="Windows NT 3.5">Windows NT 3.5</a>. However, due to performance issues of hardware of that age, it was decided to move the graphics subsystem into kernel mode. As such, system call in the range of 0x1000-0x1FFF are satisfied by win32k.sys (instead of ntoskrnl.exe as done for 0-0x0FFF), and are declared in user32.dll and gdi32.dll. These functions have the <b>NtUser</b> and <b>NtGdi</b> prefix (e.g. <b>NtUserLockWorkStation</b> and <b>NtGdiEnableEudc</b>).

</p>

<p>Uses of Native API functions includes but not limited to:

</p>

<ul><li>Enabling and disabling privileges (RtlAdjustPrivilege)</li>

<li>Creating remote threads within processes that are running in different session (RtlCreateUserThread)</li>

<li>Running native applications (RtlCreateUserProcess)</li>

<li>Performing a forced shutdown (NtShutdownSystem)</li>

<li>Causing a BSOD in User mode (NtRaiseHardError)</li>

<li>Displaying a string in Native Mode (NtDisplayString)</li></ul>
