Hi All,
XtOpenDisplay is getting thru for NULL as a
display string but I want to open with my own display
string like ":0.0" and ":0.1", but for this ":0.0" is
working but ":0.1" is getting fails what may be the
reason.
display1 = XtOpenDisplay(appcon, NULL, "test1",
"Test", NULL, 0, &argc,
argv);
(I want to use like bellow one)
display1 = XtOpenDisplay(appcon, ":0.1", "test1",
"Test", NULL, 0, &argc,
argv);
in this I want instead of NULL = ":0.0" and another as
":0.1" is it possible in Linux, if it is not then what
is the alternative for this type of opening displays.
Thanks in advance,
Bala.
