lf_scheduler_t

typedef struct lf_scheduler_t lf_scheduler_t

Paramters used in schedulers of the threaded reactor C runtime.

Note

Members of this struct are added based on existing schedulers' needs. These should be expanded to accommodate new schedulers.

Function Documentation

init_sched_instance()

bool init_sched_instance	(	struct environment_t *	env,
		lf_scheduler_t **	instance,
		size_t	number_of_workers,
		sched_params_t *	params )

Initialize instance using the provided information.

No-op if instance is already initialized (i.e., not NULL). This function assumes that mutex is allowed to be recursively locked.

Parameters

instance	The lf_scheduler_t object to initialize.
number_of_workers	Number of workers in the program.
params	Reference to scheduler parameters in the form of a sched_params_t. Can be NULL.

Returns

true if initialization was performed. false if instance is already initialized (checked in a thread-safe way).
