Parameters

  • ErrorMode
    Optional. Specified as a decimal representation of a hexadecimal bitmask. Values must be specified in decimal format. The following table shows the possible values.

    Value Name Description
    0 (0xnnnn0000) DAERH_ABORT Default. The abort-on-error mode stops the command file from processing further.
    32768 (0xnnnn8000) DAERH_IGNORE The ignore-on-error mode continues by processing the next command when an error occurs.
    32769-33023 (0x000080xx where xx!=00 is the number of retries) DAERH_RETRY_WITHIGNORE The retry-on-error with ignore mode retries the offending command up to 255 times. If the number of retries exceeds the retry count, this mode continues processing the next command.
    1-255(0x00xx where xx!=0 is the number of retries from 1-255) DAERH_RETRY_WITHABORT The retry-on-error with abort mode retries the offending command up to 255 times. If the number of retries exceeds the retry count, the command file processing halts.
    65536 – 4294901760(0xFFFFnnnn where FFFF is the delay mask in seconds) DAERH_DELAYMASK The delay error mode value is added to either the DAERH_RETRY_WITHIGNORE or the DAERH_RETRY_WITHABORT value to cause a delay between retries. This value is in seconds and has a range between 1 and 65535.

    Note   Parsing errors, especially the passing of not valid command parameters, generates an error in DAERH_ABORT error mode. With logging enabled, an appropriate error message is output to the log file.

  • hKey
    Predefined registry handles. The following table shows the values for this parameter.

    Value Name
    2147483648 HKEY_CLASSES_ROOT
    2147483649 HKEY_CURRENT_USER
    2147483650 HKEY_LOCAL_MACHINE
    2147483651 HKEY_USERS
    2147483652 HKEY_PERFORMANCE_DATA
    2147483653 HKEY_CURRENT_CONFIG

  • ExpandMode
    Optional. Specifies if the string that follows it is an environment variable that should be expanded. Can occur multiple times with this command. The following table shows the possible values.

    Value Description
    0 Does not expand the string.
    1 Device Update Agent expands the string on the embedded device.
    2 Device Update Agent script compiler expands the string on the developer computer.

  • Key
    String specifying the name of a key that this function opens or creates. This key must be a subkey of the key identified by the Key parameter.

  • FileName
    String containing the name of the file with registry information. This file is typically created by using the RegSaveKey function.

  • Flags
    The following table shows the possible values for this parameter.

    Value Name Description
    1 DAREG_WHOLE_HIVE_VOLATILE If specified, a new, volatile memory that is the only collection of registry information — a hive — is created. If REG_WHOLE_HIVE_VOLATILE is specified, the key identified by the hKey parameter must be either the HKEY_USERS or HKEY_LOCAL_MACHINE value.
    2 DAREG_REFRESH_HIVE If specified, the location of the hive the hKey parameter points to is restored immediately following the last flush. The hive must not call RegRestoreKey with DAREG_NO_LAZY_FLUSH specified as the value of this parameter, the caller must have TCB privilege, and the handle to which the hKey parameter refers must point to the root of the hive.
    4 DAREG_NO_LAZY_FLUSH If specified, the key or hive specified by the hKey parameter is flushed automatically after a regular an interval of time.
    8 DAREG_FORCE_RESTORE If specified, the restore operation is executed even if open handles exist at or beneath the location in the registry hierarchy to which the hKey parameter points.
