◆ aml_method_invocation_read()

aml_object_t * aml_method_invocation_read ( aml_term_list_ctx_t * ctx )

Reads a MethodInvocation structure from the AML byte stream.

A MethodInvocation structure is defined as MethodInvocation := NameString TermArgList.

So this is a bit confusing, but my interpretation is that despite the name, a MethodInvocation can be any object, not just methods. For example, fields. In such cases, the TermArgList is empty. Its the only thing that makes any sense when I inspect the aml bytecode as there are clearly named objects referenced in TermArgs, but there is no "child" definition that contains such a thing, atleast that i can find. But the specification says literally nothing about this. I guess you could say that any object is being "invoked" when it is being read, it just happens to not take any arguments.

The result may have the AML_OBJECT_EXCEPTION_ON_USE flag set.

Parameters

ctx	The TermList context.

Returns: On success, the object pointer storing the result. On failure, NULL and errno is set.

◆ aml_operand_read()

aml_object_t * aml_operand_read	(	aml_term_list_ctx_t *	ctx,
		aml_type_t	allowedTypes
	)

Reads an Operand structure from the AML byte stream.

An Operand structure is defined as Operand := TermArg => Integer in the spec but this must be wrong.

For example, Operand is used in the definition of DefLGreaterEqual which is defined as DefLGreaterEqual := LgreaterEqualOp Operand Operand. Clearly using the Operand structure.

However, this does not make any sense as in section 19.6.72, regarding LGreaterEqual, it states that "Source1 and Source2 must each evaluate to an integer, a string or a buffer" clearly contradicting the definition of Operand as only being able to evaluate to an integer. More examples of this can be found all over the place.

So instead we use let the caller specify what types are allowed.

Parameters

ctx	The TermList context.
out	Output pointer to be filled with the object pointer storing the result.
allowedTypes	The allowed types that the TermArg can evaluate to.

Returns: On success, 0. On failure, ERR and errno is set.
