Function Documentation

ICall_Errno ICall_abort ( void )

Aborts.

This is preferred over C runtime abort function, in an external image since the C runtime abort is only guaranteed in a root image which contains the C runtime entry function that is executed upon startup.

void* ICall_allocMsg ( size_t size )

Allocates memory block for a message.

Parameters

size	size of the message body in bytes.

Returns: pointer to the start of the message body of the newly allocated memory block, or NULL if the allocation failed.

void ICall_createRemoteTasks ( void )

Create remote tasks.

Note: One remote task shall be created per external image.
This function must be called after calling ICall_init .

The external image information must be stored either in a custom icall_addrs.h header file in an include path when ICALL_FEATURE_SEPARATE_IMGINFO compile flag is not defined, or as a set of external constants.

If ICALL_FEATURE_SEPARATE_IMGINFO compile flag is not defined, the following macros must be defined in the ICallAddrs.h file: ICALL_STACK0_ADDR, ICALL_ADDR_MAPS, ICALL_TASK_PRIORITIES and ICALL_TASK_STACK_SIZES.

If ICALL_FEATURE_SEPARATE_IMGINFO compile flag is defined, the following constants have to be linked into an image that include ICall module: ICall_imgEntries, ICall_imgTaskPriorities, ICall_imgTaskStackSizes and ICall_numImages.

ICall_Semaphore ICall_createSemaphore	(	uint_fast8_t	mode,
		int	initcount
	)

	)

Creates a new RTOS task.

Parameters

entryfn	task entry function.

ICall_Errno ICall_entityId2ServiceId	(	ICall_EntityID	entityId,
		ICall_ServiceEnum *	servId
	)

Transforms and entityId into a serviceId. Note that this function is useful in case an application waits for messages from both a server and another application, in which case, the application can only use ICall_fetchMsg , not ICall_fetchServiceMsg because the latter will return ICALL_ERRNO_CORRUPT_MSG when a message sent by the other application is about to be fetched.

Message format indicates whether and which field of the message must be transformed into a implementation specific sender identity for an external image. When a service message interface is defined, it may contain a field that is not understood by the client but only understood by the system on the server's side. The format provides an information to the messaging system on such a server so that it can generically tag necessary information to the message.
msg	pointer to the message body to send. Note that if message is successfully sent, the caller should not reference the message any longer. However, if the function fails, the caller still owns the reference to the message. That is, caller may attempt another send, or may free the memory block, etc.

Returns: ICALL_ERRNO_SUCCESS when successful; ICALL_ERRNO_INVALID_SERVICE when the 'dest' is unregistered service.; ICALL_ERRNO_INVALID_PARAMETER when the 'src' is an out of range entity id or when 'dest' is is a service that does not receive a message (such as ICall primitive service).
Note that as far as 'src' is within the range, this function won't notice the 'src' entity id as invalid.
