Advanced Configuration and Power Interface Specification
19.6.21 CreateField (Create Arbitrary Length Buffer Field)
Syntax
CreateField (SourceBuffer, BitIndex, NumBits, FieldName)
Arguments
SourceBuffer is evaluated as a buffer. BitIndex and NumBits are evaluated as integers. FieldName is
a NameString.
Description
A new buffer field object named FieldName is created for the bits of SourceBuffer at BitIndex for
NumBits. The entire bit range of the defined field within SourceBuffer must exist. If NumBits
evaluates to zero, a fatal exception is generated.
19.6.22 CreateQWordField (Create 64-Bit Buffer Field)
Syntax
CreateQWordField (SourceBuffer, ByteIndex, QWordFieldName)
Arguments
SourceBuffer is evaluated as a buffer. ByteIndex is evaluated as an integer. QWordFieldName is a
NameString.
Description
A new buffer field object named QWordFieldName is created for the QWord of SourceBuffer at the
byte index of ByteIndex. The QWord-defined field within SourceBuffer must exist.
19.6.23 CreateWordField (Create 16-Bit Buffer Field)
Syntax
CreateWordField (SourceBuffer, ByteIndex, WordFieldName)
Arguments
SourceBuffer is evaluated as a buffer. ByteIndex is evaluated as an integer. WordFieldName is a
NameString.
Description
A new bufferfield object named WordFieldName is created for the word of SourceBuffer at the byte
index of ByteIndex. The word-defined field within SourceBuffer must exist.
19.6.24 DataTableRegion (Create Data Table Operation Region)
Syntax
