ModifyWindow(D4pccard)

ModifyWindow -- describes PC Card window modifications

Syntax

   #include <sys/lcs.h>
   #include <sys/lss.h>

Description

The ModifyWindow structure is used to modify the attributes or access speed of a window that was previously allocated with the RequestWindow(D3pccard) service.

Structure definition

   unsigned short  	usAttributes;
   unsigned char   	ucAccessSpeed;

Structure members

The members are defined as:

usAttributes

Window attributes, bit mapped:

bit 0: reserved, reset to 0
bit 1: set (1) = attribute memory; reset (0) = CardBus PC Card
bit 2: set (1) = enable; reset (0) = disable
bit 3: set (1) = access speed valid; must be reset (0) = CardBus PC Card
bit 4-15: reserved, reset to 0

usAccessSpeed

Window speed, bit-mapped.

bit 0-2

device speed code if bits 3-6 are reset to 0:

1: 250 seconds
2: 200 seconds
3: 150 seconds
4: 100 seconds

If speed mantissa is not set to 0, this is the speed exponent.

bit 3-6

speed mantissa

bit 7

wait, set (1) = use WAIT# if available

Usage
