NAME

       csx_MapMemPage - map the memory area on a PC Card

SYNOPSIS

       #include <sys/pccard.h>

       int32_t csx_MapMemPage(window_handle_t wh, map_mem_page_t *mp);

INTERFACE LEVEL

       Solaris DDI Specific (Solaris DDI)

STRUCTURE MEMBERS

       The structure members of map_mem_page_t are:

       uint32_t     CardOffset;       /* card offset */
       uint32_t     Page;	      /* page number */

       The fields are defined as follows:

       CardOffset      The absolute offset in bytes from the beginning of the PC Card to map into system memory.

       Page	       Used internally by Card Services; clients must set this field to 0 before calling this function.

       CS_BAD_OFFSET		       Offset is invalid.

       CS_BAD_PAGE		       Page is not zero.

       CS_NO_CARD		       No PC Card in socket.
