_ACPI_EVAL_INPUT_BUFFER_V1 structure

-description

The ACPI_EVAL_INPUT_BUFFER structure is used as input to an IOCTL_ACPI_EVAL_METHOD request and to an IOCTL_ACPI_ASYNC_EVAL_METHOD request. The structure supplies the name of a control method that does not take an input argument.

-struct-fields

-field Signature

The signature of an input buffer that does not include an argument, which must be set to ACPI_EVAL_INPUT_BUFFER_SIGNATURE.

-field DUMMYUNIONNAME

-field DUMMYUNIONNAME.MethodName

A four-element ASCII character array that contains the name of a control method, for example, 'ABCD.'

-field DUMMYUNIONNAME.MethodNameAsUlong

A value of type ULONG that contains the name of the method in the format (ULONG) ('DCBA'), where the method name is the four-element ASCII character array 'ABCD.'

-remarks

If a device supports a control method named 'ABCD' that does not take an input argument, a driver for the device can evaluate the method by sending an IOCTL_ACPI_EVAL_METHOD request or an IOCTL_ACPI_ASYNC_EVAL_METHOD request to the device and setting the members of the input ACPI_EVAL_INPUT_BUFFER structure as follows:

  • Set Signature to ACPI_EVAL_INPUT_BUFFER_SIGNATURE.
  • Set MethodName to 'ABCD' or MethodNameAsUlong to (ULONG)('DCBA').
For more information about how to use this structure, see Evaluating ACPI Control Methods.
