The client handle must be passed to \fBcsx_DeregisterClient\fR(9F) when the client terminates. .SH STRUCTURE MEMBERS .sp .LP The structure members of \fBclient_reg_t\fR are: .sp .in +2 .nf uint32_t Attributes; uint32_t EventMask; event_callback_args_t event_callback_args; uint32_t Version; /* CS version to expect */ csfunction_t *event_handler; ddi_iblock_cookie_t *iblk_cookie; /* event iblk cookie */ ddi_idevice_cookie_t *idev_cookie; /* event idev cookie */ dev_info_t *dip; /* client's dip */ char driver_name[MODMAXNAMELEN]; .fi .in -2 .sp .LP The fields are defined as follows: .sp .ne 2 .na \fB\fBAttributes\fR\fR .ad .RS 23n This field is bit-mapped and defined as follows: .sp .ne 2 .na \fB\fBINFO_MEM_CLIENT\fR\fR .ad .sp .6 .RS 4n Memory client device driver. .RE .sp .ne 2 .na \fB\fBINFO_MTD_CLIENT\fR\fR .ad .sp .6 .RS 4n Memory Technology Driver client. .RE .sp .ne 2 .na \fB\fBINFO_IO_CLIENT\fR\fR .ad .sp .6 .RS 4n \fBIO\fR client device driver. .RE .sp .ne 2 .na \fB\fBINFO_CARD_SHARE\fR\fR .ad .sp .6 .RS 4n Generate artificial \fBCS_EVENT_CARD_INSERTION\fR and \fBCS_EVENT_REGISTRATION_COMPLETE\fR events. .RE .sp .ne 2 .na \fB\fBINFO_CARD_EXCL\fR\fR .ad .sp .6 .RS 4n Generate artificial \fBCS_EVENT_CARD_INSERTION\fR and \fBCS_EVENT_REGISTRATION_COMPLETE\fR events. .sp .ne 2 .na \fB\fBINFO_MEM_CLIENT\fR\fR .ad .br .na \fB\fBINFO_MTD_CLIENT\fR\fR .ad .br .na \fB\fBINFO_IO_CLIENT\fR\fR .ad .sp .6 .RS 4n These bits are mutually exclusive (that is, only one bit may be set), but one of the bits must be set. .RE .sp .ne 2 .na \fB\fBINFO_CARD_SHARE\fR\fR .ad .br .na \fB\fBINFO_CARD_EXCL\fR\fR .ad .sp .6 .RS 4n If either of these bits is set, the client will receive a \fBCS_EVENT_REGISTRATION_COMPLETE\fR event when Card Services has completed its internal client registration processing and after a sucessful call to \fBcsx_RequestSocketMask\fR(9F). .sp Also, if either of these bits is set, and if a card of the type that the client can control is currently inserted in the socket (and after a successful call to \fBcsx_RequestSocketMask\fR(9F)), the client will receive an artificial \fBCS_EVENT_CARD_INSERTION\fR event. .RE .RE .RE .sp .ne 2 .na \fB\fBEvent\fR \fBMask\fR\fR .ad .RS 23n This field is bit-mapped and specifies the client's global event mask. Card Services performs event notification based on this field.

Typically, this is the client driver's soft state pointer. .RE .sp .ne 2 .na \fB\fBVersion\fR\fR .ad .RS 23n This field contains the specific Card Services version number that the client expects to use. Typically, the client will use the \fBCS_VERSION\fR macro to specify to Card Services which version of Card Services the client expects. .RE .sp .ne 2 .na \fB\fBevent_handler\fR\fR .ad .RS 23n The client event callback handler entry point is passed in the \fBevent_handler\fR field. .RE .sp .ne 2 .na \fB\fBiblk_cookie\fR\fR .ad .br .na \fB\fBidev_cookie\fR\fR .ad .RS 23n These fields must be used by the client to set up mutexes that are used in the client's event callback handler when handling high priority events. .RE .sp .ne 2 .na \fB\fBdip\fR\fR .ad .RS 23n The client must set this field with a pointer to the client's dip. .RE .sp .ne 2 .na \fB\fBdriver_name\fR\fR .ad .RS 23n The client must copy a driver-unique name into this member. This name must be identical across all instances of the driver. .RE .SH RETURN VALUES .sp .ne 2 .na \fB\fBCS_SUCCESS\fR\fR .ad .RS 27n Successful operation. .RE .sp .ne 2 .na \fB\fBCS_BAD_ATTRIBUTE\fR\fR .ad .RS 27n No client type or more than one client type specified. .RE .sp .ne 2 .na \fB\fBCS_OUT_OF_RESOURCE\fR\fR .ad .RS 27n Card Services is unable to register client. .RE .sp .ne 2 .na \fB\fBCS_BAD_VERSION\fR\fR .ad .RS 27n Card Services version is incompatible with client. .RE .sp .ne 2 .na \fB\fBCS_BAD_HANDLE\fR\fR .ad .RS 27n Client has already registered for this socket. .RE .sp .ne 2 .na \fB\fBCS_UNSUPPORTED_FUNCTION\fR\fR .ad .RS 27n No \fBPCMCIA\fR hardware installed. .RE .SH CONTEXT .sp .LP This function may be called from user or kernel context. .SH SEE ALSO .sp .LP \fBcsx_DeregisterClient\fR(9F), \fBcsx_RequestSocketMask\fR(9F) .sp .LP \fIPC Card 95 Standard\fR, PCMCIA/JEIDA
