Kernel I/O Controls

This describes the KernelIoControl() functions available to application pro-

grammers. Most C++ applications need to prototype the function as the

following to avoid link and compile errors.

extern “C” BOOL KernelIoControl(DWORD dwIoControlCode, LPVOID lpInBuf, DWORD

nInBufSize, LPVOID lpOutBuf, DWORD nOutBufSize, LPDWORD lpBytesReturned);

IOCTL_HAL_GET_DEVICE_INFO

This IOCTL returns either the platform type or the OEMPLATFORM

name based on an input value.

Syntax

BOOL KernelIoControl( IOCTL_HAL_GET_DEVICE_INFO, LPVOID

lpInBuf, DWORD nInBufSize, LPVOID lpOutBuf, DWORD

nOutBufSize, LPDWORD lpBytesReturned );

Parameters

lpInBuf Points to a DWORD containing either the SPI_GETPLATFORMTYPE or

SPI_GETOEMINFO value.

lpInBufSize Must be set to sizeof(DWORD).

lpOutBuf Must point to a buffer large enough to hold the return data of the function. If

SPI_GETPLATFORMTYPE is specified in lpInBuf, then the “PocketPC\0” Unicode string is

returned. If SPI_GETOEMINFO is specified in lpInBuf, then the “Intermec 700\0” Unicode

string is returned.

nOutBufSize The size of lpOutBuf in bytes. Must be large enough to hold the string returned.

lpBytesReturned The actual number of bytes returned by the function for the data requested.

Return Values

Returns TRUE if function succeeds. Returns FALSE if the function fails.

GetLastError() may be used to get the extended error value.
