Post xlib to create window

i want to create an irregular window using xlib, i use the function: XShapeCombineMask(dpy, win, ShapeBounding, 0, 0, px);

but when i running this application, an error accrues:
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 128 (SHAPE)
Minor opcode of failed request: 2 (X_ShapeMask)
Serial number of failed request: 22
Current serial number in output stream: 24
and this the codes:
win = XCreateWindow(dpy,
100, 100 ,
w, h,
XDefaultDepth(dpy, screen_num),
CWBackingStore | CWBackPixel | CWOverrideRedirect,
RGB rgb[h][w];
memset(rgb, 0, sizeof(RGB) *w * h);
GC gc = XCreateGC(dpy, win, 0, NULL);
char *image32=( char *)malloc(w*h*4);
XImage *im = XCreateImage(dpy, DefaultVisual(dpy, screen_num), 24, ZPixmap, 0, image32, w, h, 32, 0);
unsigned long bk = 0;
if(im == NULL)
return -1;
for(int m = 0; m < h; m++)
for(int n = 0; n < w; n++)
fread((void *)&rgb[m][n], 1, sizeof(RGB), fp);
bk = (rgb[m][n].r<<16) + (rgb[m][n].g<<8) + (rgb[m][n].b);
XPutPixel(im, n, m, bk);

Pixmap px = XCreatePixmap(dpy, win, w, h, 24);
XPutImage(dpy, px, gc, im, 0, 0, 0, 0, w, h);
int t;
XWMHints wmHints;
wmHints.flags = StateHint;
wmHints.initial_state = NormalState;
XSetWMProperties(dpy, win, NULL, NULL, NULL, 0, NULL,
&wmHints, NULL);
XSetTransientForHint(dpy, win, win);
//char *name = "test";
//XQueryExtension(dpy, name, &t, &t, &t);
if(XShapeQueryExtension(dpy, &t, &t) == false)
return -1;
printf("%d\n", t);
XShapeCombineMask(dpy, win, ShapeBounding, 0, 0, px, ShapeSet);
Guys, who can give me some suggestions or codes to do the work.
tks,best wishs.
