 csx_ModifyWindow 9F "19 Jul 1996" "SunOS 5.11" "Kernel Functions for Drivers"
 NAME
csx_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 window to Common
Memory.


WIN_MEMORY_TYPE_AM

Window points to Attribute Memory area. Set this to map the window to Attribute
Memory.


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 mantissa is 0 (noted as reserved in the
PC Card 95 Standard), 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_ConvertSpeed(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.
