GetNativeSystemInfo function (sysinfoapi.h)
Retrieves information about the current system to an application running under WOW64. If the function is called from a 64-bit application, it is equivalent to the GetSystemInfo function. If the function is called from an x86 or x64 application running on a 64-bit system that does not have an Intel64 or x64 processor (such as ARM64), it will return information as if the system is x86 only if x86 emulation is supported (or x64 if x64 emulation is also supported).
Syntax
void GetNativeSystemInfo(
[out] LPSYSTEM_INFO lpSystemInfo
);
Parameters
[out] lpSystemInfo
A pointer to a SYSTEM_INFO structure that receives the information.
Return value
None
Remarks
To determine if a Win32-based application is running under WOW64 (or if a 64-bit system does not have an Intel64 or x64 processor), call the IsWow64Process2 function.
To compile an application that uses this function, define _WIN32_WINNT as 0x0501 or later. For more information, see Using the Windows Headers.
Examples
For an example, see Getting the System Version.
