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

csx_Parse_CISTPL_FUNCID - parse Function Identification tuple

#include <sys/pccard.h>
int32_t csx_Parse_CISTPL_FUNCID(client_handle_t ch, tuple_t *tu,
     cistpl_funcid_t *cf);

illumos DDI Specific (illumos DDI)

ch
Client handle returned from csx_RegisterClient(9F).

tu

Pointer to a tuple_t structure (see tuple(9S)) returned by a call to csx_GetFirstTuple(9F) or csx_GetNextTuple(9F).

cf

Pointer to a cistpl_funcid_t structure which contains the parsed CISTPL_FUNCID tuple information upon return from this function.

This function parses the Function Identification tuple, CISTPL_FUNCID, into a form usable by PC Card drivers.

The CISTPL_FUNCID tuple is used to describe information about the functionality provided by a PC Card. Information is also provided to enable system utilities to decide if the PC Card should be configured during system initialization. If additional function specific information is available, one or more function extension tuples of type CISTPL_FUNCE follow this tuple (see csx_Parse_CISTPL_FUNCE(9F)).

The structure members of cistpl_funcid_t are:


uint32_t     function;     /* PC Card function code */
uint32_t     sysinit;      /* system initialization mask */

The fields are defined as follows:
