Function Documentation

int controller_address

(

struct sockaddr_in *

addr

)

Gets the sockaddr associated with the global controller.

Parameters

addr	Output parameter to be filled with controller's ip and port

Returns

0 on success, -1 on error

Definition at line 77 of file runtime_dfg.c.

void free_runtime_dfg

(

)

Frees the runtime's static instance of the DFG.

Definition at line 119 of file runtime_dfg.c.

struct dedos_dfg* get_dfg

(

)

Returns

the DFG with which this runtime was instantiated

Definition at line 115 of file runtime_dfg.c.

int init_runtime_dfg	(	char *	filename,
		int	runtime_id
	)

Initializes the DFG as loaded from a JSON file, and sets the global variables such that the DFG and runtime can be accessed.

Parameters

filename	File from which to load the json DFG
runtime_id	Idenitifer for this runtime

Returns

0 on success, -1 on error

Definition at line 41 of file runtime_dfg.c.

int local_runtime_id

(

)

Returns

the ID of the local runtime

Definition at line 91 of file runtime_dfg.c.

uint32_t local_runtime_ip

(

)

Definition at line 107 of file runtime_dfg.c.

int local_runtime_port

(

)

Returns

the port on which the local runtime is listening

Definition at line 99 of file runtime_dfg.c.

void set_local_runtime

(

struct dfg_runtime *

rt

)

Sets the local runtime to be equal to the provided rt.

Really should only be used from testing. Use init_runtime_dfg instead

Definition at line 37 of file runtime_dfg.c.

Variable Documentation

struct dedos_dfg* DFG = NULL

static

Static (global) variable for accessing a lodaed Dfg.

Definition at line 33 of file runtime_dfg.c.

struct dfg_runtime* LOCAL_RUNTIME = NULL

static

Static (global) variable holding this runtime's dfg.

Definition at line 35 of file runtime_dfg.c.
