CSX_VALIDATECIS(9F) Kernel Functions for Drivers CSX_VALIDATECIS(9F)

csx_ValidateCIS - validate the Card Information Structure (CIS)

#include <sys/pccard.h>
int32_t csx_ValidateCIS(client_handle_t ch, cisinfo_t *ci);

illumos DDI Specific (illumos DDI)

Client handle returned from csx_RegisterClient(9F).


Pointer to a cisinfo_t structure.

This function validates the Card Information Structure (CIS) on the PC Card in the specified socket.

The structure members of cisinfo_t are:

 uint32_t     Socket;    /* socket number to validate CIS on */
  uint32_t     Chains;    /* number of tuple chains in CIS */
  uint32_t     Tuples;    /* total number of tuples in CIS */

The fields are defined as follows:


Not used in illumos, but for portability with other Card Services implementations, it should be set to the logical socket number.


This field returns the number of valid tuple chains located in the CIS. If 0 is returned, the CIS is not valid.


This field is an illumos-specific extension and it returns the total number of tuples on all the chains in the PC Card's CIS.

Successful operation.


No CIS on PC Card or CIS is invalid.


No PC Card in socket.


No PCMCIA hardware installed.

This function may be called from user or kernel context.
