Hi all:
I have some problems to make XGetInputFocus work...
this core compiles.. with
g++ -I/usr/local/include -g -I/usr/X11R6/include -L/usr/local/lib -lX11
-L/usr/X11R6/lib xtest.c
but it gives out core dump when runs, after tracing a while, it is
somewhere inside the API XGetInputFocus. Can someone give me a hand???
Thanks!!!
regards
leo

int* ts=NULL;
//get the displayname
if (argc>1) {
for (i=1; i<argc; i++) {
if (strcmp(argv[i], "-display")==0|| strcmp(argv[i], "--display")==0)
{
i++;
if (i>=argc) {
printf(("too few arguments for %s"), argv[i-1]);
exit(1);
}
DisplayName = argv[i];
}
}
}
//init X connection
dpy =XOpenDisplay(DisplayName);
//I am sure the dpy* is not null here!!
if (dpy){
//core dump!!
XGetInputFocus(dpy, w,&re);
}
return 0;
}
