CSX_MODIFYWINDOW(9F)CSX_MODIFYWINDOW(9F)NAMEcsx_ModifyWindow - modify window attributes
SYNOPSIS
#include <sys/pccard.h>
int32_t csx_ModifyWindow(window_handle_t wh, modify_win_t *mw);
INTERFACE LEVEL
Solaris DDI Specific (Solaris DDI)
PARAMETERS
wh
Window handle returned from csx_RequestWindow(9F).
mw
Pointer to a modify_win_t structure.
DESCRIPTION
This function modifies the attributes of a window allocated by the
csx_RequestWindow(9F) function.
Only some of the window attributes or the access speed field may be
modified by this request. The csx_MapMemPage(9F) function is also used
to set the offset into PC Card memory to be mapped into system memory
for paged windows. The csx_RequestWindow(9F) and csx_ReleaseWindow(9F)
functions must be used to change the window base or size.
STRUCTURE MEMBERS
The structure members of modify_win_t are:
uint32_t Attributes; /* window flags */
uint32_t AccessSpeed; /* window access speed */
The fields are defined as follows:
Attributes
This field is bit-mapped and defined as follows:
WIN_MEMORY_TYPE_CM
Window points to Common Memory
area. Set this to map the win‐
dow to Common Memory.
WIN_MEMORY_TYPE_AM
Window points to Attribute
Memory area. Set this to map
the window to Attribute Mem‐
ory.
WIN_ENABLE
Enable Window. The client must
set this to enable the window.
WIN_ACCESS_SPEED_VALID
AccessSpeed valid. The client
must set this when the
AccessSpeed field has a value
that the client wants set for
the window.
AccessSpeed
The bit definitions for this field use the format of the
extended speed byte of the Device ID tuple. If the man‐
tissa is 0 (noted as reserved in the PC Card 95 Stan‐
dard), the lower bits are a binary code representing a
speed from the list below. Numbers in the first column
are codes; items in the second column are speeds.
0
Reserved: do not use
1
250 nsec
2
200 nsec
3
150 nsec
4
100 nsec
5 - 7
Reserved: do not use
It is recommended that clients use the csx_Convert‐
Speed(9F) function to generate the appropriate
AccessSpeed values rather than manually perturbing the
AccessSpeed field.
RETURN VALUES
CS_SUCCESS
Successful operation.
CS_BAD_HANDLE
Window handle is invalid.
CS_NO_CARD
No PC Card in socket.
CS_BAD_OFFSET
Error getting/setting window hardware
parameters.
CS_BAD_WINDOW
Error getting/setting window hardware
parameters.
CS_BAD_SPEED
AccessSpeed is invalid.
CS_UNSUPPORTED_FUNCTION
No PCMCIA hardware installed.
CONTEXT
This function may be called from user or kernel context.
