CardRequestSocketMask

This function associates a socket and function pair with an event mask for the driver. Card Services then restricts its future callbacks to the driver to those associated with the event mask passed to the CardRequestSocketMask function.

Syntax

STATUS CardRequestSocketMask( CARD_CLIENT_HANDLE hCardClient CARD_SOCKET_HANDLE hSock UINT16 fEventMask );

Parameters

hCardClient: Client handle obtained from the CardRegisterClient function.
hSock: Handle to a socket and function pair.
fEventMask: Specifies a bitmask indicating the events that trigger a callback. The allowable card events are listed in the Cardserv.h header file.

Return Values

CERR_SUCCESS indicates success. One of the following values indicates failure:

CERR_BAD_HANDLE: Indicates that the driver handle specified for hCardClient is invalid.
CERR_BAD_SOCKET: Indicates that the socket identifier specified for hSock is invalid.

Remarks

An event mask should not be confused with the global event mask, which pertains to all sockets and is set by CardRegisterClient.

The CardSetEventMask function can change either a socket-specific event mask or the mask specified by CardRegisterClient.
