Function Documentation

aml_state_init()

uint64_t aml_state_init	(	aml_state_t *	state,
		aml_object_t **	args
	)

Initialize an AML state.

Parameters

state	Pointer to the state to initialize.
args	Array of pointers to the objects to pass as arguments, or NULL. Must be null-terminated.

Returns

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

aml_state_deinit()

void aml_state_deinit

(

aml_state_t *

state

)

Deinitialize an AML state.

Parameters

state

Pointer to the state to deinitialize.

aml_state_result_get()

aml_object_t * aml_state_result_get

(

aml_state_t *

state

)

Get the result object of the state.

If no result is available, a Integer object with value 0 is returned.

See also

aml_method_invoke() for more details.

Parameters

state

Pointer to the state.

Returns

On success, a copy of the result object. On failure, NULL and errno is set.

Here is the caller graph for this function:

aml_state_result_set()

void aml_state_result_set	(	aml_state_t *	state,
		aml_object_t *	result
	)

Set the result object of the state.

Note that methods are supposed to return copies of objects, not references to existing objects. However, due to the behaviour of implicit returns, always returning the last evaluated object, means there is no way for the object to be modified between this function being called and the method returning. So in this case it is acceptable to store a reference to the object and only make a copy when the method actually returns.

aml_method_invoke() for more details.

Parameters

state	Pointer to the state.
result	Pointer to the result object, or NULL to clear the result.
