XGetIconSizes()XGetIconSizes()NameXGetIconSizes – get preferred icon sizes.
Synopsis
Status XGetIconSizes(display, w, size_list_return, count_return)
Display *display;
Window w;
XIconSize **size_list_return;
int *count_return;
Arguments
display Specifies a connection to an X server; returned from XOpenDis‐
play().
w Specifies the window ID (usually of the root window).
size_list_return
Returns a pointer to the size list.
count_return
Returns the number of items in the size list.
Returns
Zero on failure, non-zero on success.
DescriptionXGetIconSizes() reads the XA_WM_ICON_SIZE property that should be set
by the window manager to specify its desired icon sizes. XGetIcon‐
Sizes() returns a Status of zero if a window manager has not set icon
sizes, and a non-zero Status otherwise. This function should be called
by all programs to find out what icon sizes are preferred by the window
manager. The application should then use 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 XFree().

cation.
