This IOCTL is a request by an application to retrieve microprocessor information from the OAL and store it in the PROCESSOR_INFO structure.

This IOCTL is optional, but Microsoft recommends that all OEMs support it. Applications that need this information use the KernelIoControl function to query the OEM for information.

  • nInBufsize
    [in] Set to zero.

  • lpOutBuf
    [out] Pointer to the output buffer.

    This is set to a buffer allocated to hold the PROCESSOR_INFO structure.

  • nOutBufSize
    [in] Maximum number of bytes that can be returned in lpOutBuf.

    Set to the size of the PROCESSOR_INFO structure.

  • lpBytesReturned
    [in] Actual number of bytes returned in lpOutBuf.
