Question about X window system "XmCreateMainWindow"

[Guest three_white]

Hi, I'm dealing with a problem on Linux (Red Hat 4.4.7-4) which is related to X window system. In my program, I use:

 

"main_w = XmCreateMainWindow (toplevel, "main_w", NULL, 0);"

 

to create a main window and I find that the window id value of the first child of main_w is a very large integer "267110801680". I use the command below to find this number

 

when I debug it in DDD:

 

print *(((CompositeWidget) main_w)->composite)->children[0]

 

This large integer results in a memory problem when I use Valgrind to check the memory leakage which is "Invalid read".

 

The abnormal large integer should be a return value from "XmCreateMainWindow" and is it related to my operating system?
