Function Documentation

◆ HOST_Configure()

int32_t HOST_Configure	(	host_interface_handle_t *	pHandle,
		void *	pConfigData
	)

The function to Configure the Host.

TBD

Parameters

[in]	pHandle	- pointer to the interface handle
[in]	pConfigData	- Host configuration information

Returns: HOST_Configure() returns the status .

◆ HOST_Initialize()

int32_t HOST_Initialize	(	host_interface_handle_t *	pHandle,
		comm_type_t	type,
		void *	pCommInstance,
		comm_instance_type_t	inType,
		Host_Event_t	event,
		void *	pInData
	)

The function to Initialize the Host.

It initialize the host for the specified communucation channel and data format service.

Parameters

[in]	pHandle	- pointer to the interface handle
[in]	type-	host communication type
[in]	pCommInstance	- pointer to a communication object.
[in]	inType	- instanceType.
[in]	event	- event handler callback
[in]	pInData	- input data to underlying layers

Returns: HOST_Initialize() returns the status .

Constraints:: None

Reentrant: Yes

◆ HOST_Receive()

int32_t HOST_Receive	(	host_interface_handle_t *	pHandle,
		uint8_t *	pData,
		uint32_t *	pRecvSize,
		uint32_t	size,
		BlockRead_t	process
	)

The function to receive data from the host.

BlockRead callback function will be called only if Host is initialized with Blocking Call communication instance, refer comm_instance_type_t inType HOST_Initialize() function. If the host is initialized with blocking communication instance, This call will be blocked until BlockRead_t process returns provided BlockRead_t process is not NULL else it will be blocked until specified number of requested bytes are received. User can implement own logic to separate packet start and end de-limiter in BlockRead_t process to determine a stream or use provided Block Read function in the each Data Format. If the host is intialized with NonBlocking Communication instance. This call will be immediately returns and Users Needs to Syschronous data based on Host event HOST_INTERFACE_EVENT_RECEIVE_COMPLETE.

Parameters

[in]	pHandle	- pointer to the interface handle.
[out]	pData	- pointer to data to be received.
[out]	pRecvSize	- number of byte received. This field is for the future use.
[in]	size	- Nnumber of byte intend to receive, if user know. This argument has no impact if "BlockRead_t process" is not NULL and communication instance is Blocking
[in]	process	- process function for the block data read. NOTE: This parameter is not valid, if communication Read function is Nonblocking. The logic in the callback can start and end packet data detection to get the unknown receive length stream data from the host.
