.SH NAME
XAllocIconSize, XSetIconSizes, XGetIconSizes, XIconSize \- allocate icon size structure and set or read a window's WM_ICON_SIZES property
.SH SYNTAX
XIconSize *XAllocIconSize\^(void\^);
.LP
int XSetIconSizes\^(\^Display *\fIdisplay\fP, Window \fIw\fP, XIconSize
*\fIsize_list\fP, int \fIcount\fP\^);
.LP
Status XGetIconSizes\^(\^Display *\fIdisplay\fP, Window \fIw\fP, XIconSize
**\fIsize_list_return\fP, int \fIcount_return\fP\^);
.SH ARGUMENTS
.IP \fIdisplay\fP 1i
Specifies the connection to the X server.
.IP \fIcount\fP 1i
Specifies the number of items in the size list.
.IP \fIcount_return\fP 1i
Returns the number of items in the size list.
.IP \fIsize_list\fP 1i
Specifies the size list.
.IP \fIsize_list_return\fP 1i
Returns the size list.
.IP \fIw\fP 1i
Specifies the window.
.SH DESCRIPTION
The
.ZN XAllocIconSize 
function allocates and returns a pointer to a
.ZN XIconSize 
structure.
Note that all fields in the
.ZN XIconSize
structure are initially set to zero.
If insufficient memory is available, 
.ZN XAllocIconSize
returns NULL.
To free the memory allocated to this structure,
use
.ZN XFree .
.LP
The
.ZN XSetIconSizes
function is used only by window managers to set the supported icon sizes.
.LP
.ZN XSetIconSizes
can generate
.ZN BadAlloc
and
.ZN BadWindow
errors.
.LP
The
.ZN XGetIconSizes
function returns zero if a window manager has not set icon sizes;
otherwise, it return nonzero.
.ZN XGetIconSizes
should be called by an application that
wants to find out what icon sizes would be most appreciated by the
window manager under which the application is running.
The application
should then use
.ZN XSetWMHints
to supply the window manager with an icon pixmap or window in one of the
supported sizes.
To free the data allocated in size_list_return, use
.ZN XFree .
.LP
.ZN XGetIconSizes
can generate a
.ZN BadWindow
error.
.SH PROPERTIES
.TP 1i
\s-1WM_ICON_SIZES\s+1
The window manager may set this property on the root window to
specify the icon sizes it supports.
The C type of this property is 
.ZN XIconSize .
.SH STRUCTURES
The
.ZN XIconSize
structure contains:
.LP
.IN "XIconSize" "" "@DEF@"
.Ds 0
typedef struct {
        int min_width, min_height;
        int max_width, max_height;
        int width_inc, height_inc;
} XIconSize;
.De
.LP
The width_inc and height_inc members define an arithmetic progression of
sizes (minimum to maximum) that represent the supported icon sizes.
.SH DIAGNOSTICS
.TP 1i
.ZN BadAlloc
The server failed to allocate the requested resource or server memory.
.TP 1i
.ZN BadWindow
A value for a Window argument does not name a defined Window.
