Get Pattern Registration Key

 	int mgetkey(UINT32& keysize,char* key);
	Input:
	UINT32&		keysize;		size of the key buffer
                                UINT32 is unsigned int
	char* 		key;			buffer to retrieve the key
	Output:
	UINT32&		keysize;		size of the retrieved key
	Return value:
	1.....succeeded in retrieving
	0.....not found
	negative number....BUFFER_OVERFLOW
			The size of the key exceeds keysize. In this case, the actual key size
			is assigned to keysize and returned.
