ClientHandle -- defines which client to handle

Syntax

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

Description

The ClientHandle structure is assigned by CardServices( ) and used internally to define the client to handle and the current state of that client.

Structure definition

The ClientHandle structure contains the following members:

   ClientHandle_t         *next;
   unsigned short         usSocket;
   DevInfo_t              *pClientName;
   unsigned short         usAttributes;
   unsigned short         usState;
   unsigned short         usEventMask;
   unsigned short         usSocketMask;
   unsigned short         usCallbackState;
   ClientData_t           ClientData;
   CallbackEntry_t        pfCallbackHandler;

Structure members

The members are defined as:

next: Pointer to the next ClientHandle structure on the list.
usSocket: Set to 0 or 1, logical socket
pClientNam: Pointer to the client's name.
usAttributes: Client's attributes.
usState: State of the client driver.
usEventMask: Event mask that will not generate events to client driver.
usCallbackState: Callback state of the client driver.
ClientData: Pointer to the ClientData(D4pccard) structure that is passed to the client driver.
pfCallbackHandler: Pointer to the callback CallbackEntry(D4pccard) structure.
