csx_MapMemPage - map the memory area on a PC Card
#include <sys/pccard.h>
int32_t csx_MapMemPage(window_handle_t wh, map_mem_page_t *mp);
illumos DDI Specific (illumos DDI)
wh
Window handle returned from csx_RequestWindow(9F).
mp
Pointer to a map_mem_page_t structure.
This function maps the memory area on a PC Card into a page of a
window allocated with the csx_RequestWindow(9F) function.
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_SUCCESS
Successful operation.
CS_BAD_HANDLE
Client handle is invalid.
CS_BAD_OFFSET
Offset is invalid.
CS_BAD_PAGE
Page is not zero.
CS_NO_CARD
No PC Card in socket.
CS_UNSUPPORTED_FUNCTION
No PCMCIA hardware installed.
This function may be called from user or kernel context.
