Retrieves the path of the system directory used by WOW64, using the specified image file machine type. This directory is not present on 32-bit Windows.
UINT GetSystemWow64Directory2A( LPSTR lpBuffer, UINT uSize, WORD ImageFileMachineType );
A pointer to the buffer to receive the path. This path does not end with a backslash.
The maximum size of the buffer, in TCHARs.
An IMAGE_FILE_MACHINE_* value that specifies the machine to test.
If the function succeeds, the return value is the length, in TCHARs, of the string copied to the buffer, not including the terminating null character. If the length is greater than the size of the buffer, the return value is the size of the buffer required to hold the path.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
On systems that support multiple WOW64 architectures, you can use GetSystemWow64Directory2 to retrieve appropriate system directory associated with the WOW64 architecture specified by ImageFileMachineType.
WOW64 uses the system directory to store shared 32-bit code on 64-bit Windows. Most applications have no need to access this directory explicitly.
