.SH DESCRIPTION
This function modifies the attributes of a window allocated by the
\fBcsx_RequestWindow\fR(9F) function.
.sp
.LP
Only some of the window attributes or the access speed field may be modified by
this request. The \fBcsx_MapMemPage\fR(9F) function is also used to set the
offset into \fBPC \fRCard memory to be mapped into system memory for paged
windows. The \fBcsx_RequestWindow\fR(9F) and \fBcsx_ReleaseWindow\fR(9F)
functions must be used to change the window base or size.
.SH STRUCTURE MEMBERS
The structure members of \fBmodify_win_t\fR are:
.sp
.in +2
.nf
uint32_t       Attributes;          /* window flags */
uint32_t       AccessSpeed;         /* window access speed */

Window points to Common Memory area. Set this to map the window to Common
Memory.
.RE

Enable Window. The client must set this to enable the window.
.RE

.sp
.ne 2
.na
\fBWIN_ACCESS_SPEED_VALID\fR
.ad
.RS 26n
\fBAccessSpeed\fR valid. The client must set this when the \fBAccessSpeed\fR
field has a value that the client wants set for the window.

.RS 15n
The bit definitions for this field use the format of the extended speed byte of
the Device \fBID \fRtuple. If the mantissa is \fB0\fR (noted as reserved in the
\fIPC Card 95 Standard\fR), 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.

It is recommended that clients use the \fBcsx_ConvertSpeed\fR(9F) function to
generate the appropriate \fBAccessSpeed\fR values rather than manually
perturbing the \fBAccessSpeed\fR field.
