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

NAME

       csx_ValidateCIS - validate the Card Information Structure (CIS)

SYNOPSIS

       #include <sys/pccard.h>

       int32_t csx_ValidateCIS(client_handle_t ch, cisinfo_t *ci);

INTERFACE LEVEL

       Solaris DDI Specific (Solaris DDI)

PARAMETERS

       ch	Client handle returned from csx_RegisterClient(9F).

       ci	Pointer to a cisinfo_t structure.

DESCRIPTION

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

STRUCTURE MEMBERS

       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:

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

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

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

RETURN VALUES

       CS_SUCCESS			       Successful operation.

       CS_NO_CIS			       No CIS on PC Card or CIS is invalid.

       CS_NO_CARD			       No PC Card in socket.

       CS_UNSUPPORTED_FUNCTION		       No PCMCIA hardware installed.

CONTEXT

       This function may be called from user or kernel context.
