#include <sys/pccard.h> int32_t csx_RegisterClient(client_handle_t *ch, client_reg_t *cr);
Pointer to a client_handle_t structure.
Pointer to a client_reg_t structure.
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];
The fields are defined as follows: Attributes
This field is bit-mapped and defined as follows: INFO_MEM_CLIENT
Memory client device driver.
Memory Technology Driver client.
IO client device driver.
Generate artificial CS_EVENT_CARD_INSERTION and CS_EVENT_REGISTRATION_COMPLETE events.
Generate artificial CS_EVENT_CARD_INSERTION and CS_EVENT_REGISTRATION_COMPLETE events. INFO_MEM_CLIENT
INFO_MTD_CLIENT
INFO_IO_CLIENT
These bits are mutually exclusive (that is, only one bit may be set), but one of the bits must be set.
INFO_CARD_EXCL
If either of these bits is set, the client will receive a CS_EVENT_REGISTRATION_COMPLETE event when Card Services has completed its internal client registration processing and after a successful call to csx_RequestSocketMask(9F). 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 csx_RequestSocketMask(9F)), the client will receive an artificial CS_EVENT_CARD_INSERTION event.
This field is bit-mapped and specifies the client's global event mask. Card Services performs event notification based on this field. See csx_event_handler(9E) for valid event definitions and for additional information about handling events.
The event_callback_args_t structure members are:
void *client_data;The client_data field may be used to provide data available to the event handler (see csx_event_handler(9E)). Typically, this is the client driver's soft state pointer.
This field contains the specific Card Services version number that the client expects to use. Typically, the client will use the CS_VERSION macro to specify to Card Services which version of Card Services the client expects.
The client event callback handler entry point is passed in the event_handler field.
idev_cookie
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.
The client must set this field with a pointer to the client's dip.
The client must copy a driver-unique name into this member. This name must be identical across all instances of the driver.
Successful operation.
No client type or more than one client type specified.
Card Services is unable to register client.
Card Services version is incompatible with client.
Client has already registered for this socket.
No PCMCIA hardware installed.
