Tuple(D4pccard)

Tuple -- element of a CIS to specify capabilities of a PC Card

Syntax

   #include <sys/lcs.h>
   #include <sys/lss.h>

Description

The Tuple structure is used to determine the capabilities of a card from an element of the PC Card's CIS.

Structure definition

   unsigned short  		usSocket;
   unsigned short  		usAttributes;
   unsigned char   		ucDesiredTuple;
   unsigned char   		ucReserved;
   unsigned short  		usFlags;
   unsigned long   		ulLinkOffset;
   unsigned long   		ulCISOffset;
   unsigned char   		ucTupleCode;
   unsigned char   		ucTupleLink;

Structure members

The members are defined as:

usSocket: usSocket is two bytes long. The more significant byte indicates the function. The function of single function cards is mapped to zero. The functions of multi-function cards are enumerated from zero on up to the number of functions available less one. The low byte in usSocket indicates logical socket.
usAttributes: Bit 0 is set to 1 to return link tuples.
ucDesiredTuple
ucReserved: Reset these bits to 0.
usFlags: CardServices tuple flags data.
ulLinkOffset: CardServices link state information
ulCISOffset: CardServices CIS state information.
ucTupleCode: Tuple found.
ucTupleLink: Link value for found tuple.
