GetSetEventMask -- describe event

Syntax

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

Description

The GetSetEventMask structure is used by the GetEventMask(D3pccard) service to describe an event.

Structure definition

   unsigned short      	usAttributes;
   unsigned short      	usEventMask;
   unsigned short      	usSocket;

Structure members

The members are defined as:

usAttributes

Identifies the type of event mask to be changed. usAttributes is bitmapped. If bit 0 is reset to 0, the change is for the global event mask, whereas if bit 0 is set to 1, the change is for the specified socket only. Bit 0 indicates event mask for socket and function.

usEventMask

Identifies the event for which notification is being sent. Valid values are:

0: write protect
1: card lock change
2: ejection request
3: insertion request
4: dead battery
5: low battery
6: ready change
7: card detect change
8: power management change
9: reset events
10: Socket Services update
11: request attention change
12-15: reserved

usSocket

Identifies the card function being passed. 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 the logical socket.
