19.6.13 ConcatenateResTemplate (Concatenate Resource Templates)
Syntax
ConcatenateResTemplate (Source1, Source2, Result) => Buffer
Arguments
Source1 and Source2 are evaluated as Resource Template buffers.
Description
The resource descriptors from Source2 are appended to the resource descriptors from Source1. Then
a new end tag and checksum are appended and the result is stored in Result, if specified. If either
Source1 or Source2 is exactly 1 byte in length, a run-time error occurs. An empty buffer is treated as
a resource template with only an end tag.
19.6.14 CondRefOf (Create Object Reference Conditionally)
Syntax
CondRefOf (Source, Result) => Boolean
Arguments
Attempts to create a reference to the Source object. The Source of this operation can be any object
type (for example, data package, device object, and so on), and the result data is optionally stored
into Result.
Description
On success, the Destination object is set to refer to Source and the execution result of this operation
is the value True. On failure, Destination is unchanged and the execution result of this operation is
the value False. This can be used to reference items in the namespace that may appear dynamically
(for example, from a dynamically loaded definition block).
CondRefOf is equivalent to RefOf except that if the Source object does not exist, it is fatal for
RefOf but not for CondRefOf.
19.6.15 Connection (Declare Field Connection Attributes)
Syntax
Connection (ConnectionResourceObj)
Arguments
ConnectionResourceObj is a GPIO or Serial Bus Connection Descriptor depending on the Operation
Region type, or a named object containing the Descriptor
See Section 6.4.3.8.2, "Connection Resource Descriptors" and Section 19.6.46 "Field (Declare Field
Objects)" for more information.
