Typedef Documentation

cp_event_callback_t

typedef int(* cp_event_callback_t) (void *arg, int pd, struct osdp_event *ev)

Callback for CP event notifications.

After it has been registered with osdp_cp_set_event_callback, this method is invoked when the CP receives an event from the PD.

Parameters

arg	Opaque pointer provided by the application during callback registration.
pd	the offset (0-indexed) of this PD in kconfig OSDP_PD_ADDRESS_LIST
ev	pointer to osdp_event struct (filled by libosdp).

Return values

0	on handling the event successfully.
-ve	on errors.

pd_command_callback_t

typedef int(* pd_command_callback_t) (void *arg, struct osdp_cmd *cmd)

Callback for PD command notifications.

After it has been registered with osdp_pd_set_command_callback, this method is invoked when the PD receives a command from the CP.

Parameters

arg	pointer that will was passed to the arg param of osdp_pd_set_command_callback.
cmd	pointer to the received command.

Return values

0	if LibOSDP must send a osdp_ACK response
-ve	if LibOSDP must send a osdp_NAK response
+ve	and modify the passed struct osdp_cmd *cmd if LibOSDP must send a specific response. This is useful for sending manufacturer specific reply osdp_MFGREP.

Function Documentation

osdp_cp_send_command()

int osdp_cp_send_command	(	int	pd,
		struct osdp_cmd *	cmd
	)

Generic command enqueue API.

Parameters

pd	the offset (0-indexed) of this PD in kconfig OSDP_PD_ADDRESS_LIST
cmd	command pointer. Must be filled by application.

Return values

0	on success
-1	on failure

Note

This method only adds the command on to a particular PD's command queue. The command itself can fail due to various reasons.

osdp_cp_set_event_callback()

void osdp_cp_set_event_callback	(	cp_event_callback_t	cb,
		void *	arg
	)

Set callback method for CP event notification.

This callback is invoked when the CP receives an event from the PD.

Parameters

cb	The callback function's pointer
arg	A pointer that will be passed as the first argument of cb
