void* dtcvec_alloc

(

size_t

size

)

DTC - DATA TRANSFER CONTROLLER.

DTC manipulation with the vector table. Allocate memory for the register information. Its not necessary, but may be a good idea to do so.

Parameters:

size

number of blocks (each 12Bytes)

Returns:

pointer to register information

Here is the caller graph for this function:

void dtcvec_fillreg	(	void *	vect,
		struct dtcvec_reginfo *	reginfo
	)

Fill the register memory with the prepared data structure of register information (align bytes correctly in the memory).

Parameters:

	*vect	pointer to register information memory.
	*reginfo	data structure of register information.

Here is the caller graph for this function:

void* dtcvec_get

(

int

vectnum

)

Get address of the register information from the vector table.

Parameters:

vectnum

vector number

Returns:

pointer to register information

Here is the caller graph for this function:

void dtcvec_print

(

)

Here is the call graph for this function:

void* dtcvec_set	(	int	vectnum,
		void *	vect
	)

Assign the DTC vector address to appropriate register information.

Parameters:

	vectnum	vector number
	*vect	pointer to register information

Returns:

the old vector
