NAME

	GetCardMap -- Obtain pointer to CardMemoryMap structure

SYNOPSIS

	pointer=GetCardMap()
	d0
	struct CardMemoryMap *GetCardMap( void );

FUNCTION

	Obtain pointer to a CardMemoryMap structure.  The structure
	is READ only.
	Devices should never assume credit-card memory appears
	at any particular place in memory.  By using this function
	to obtain pointers to the base memory locations of the various
	credit-card memory types, your device will continue to work
	properly should credit cards appear in different memory
	locations in future hardware.

RESULT

	Pointer to CardMemoryMap structure -
		struct CardMemoryMap {
		UBYTE	*cmm_CommonMemory;
		UBYTE	*cmm_AttributeMemory;
		UBYTE	*cmm_IOMemory;
		};
	As of card.resource V39, this structure has been extended to
	include the size of these memory regions.  See card.h/card.i
	for the new fields.  If card.resource V39, use the constants
	in the CardMemoryMap structure rather than hard coded constants
	for memory region size.

NOTES

	If any pointer in the structure is NULL, it means this type
	of credit-card memory is not being made available.
