  12. Hi Netters,
  13.     I'm having problems doing xwdump of a window within a motif application
  14. program. The program goes something like this
  15.     
  16.             Widget xwdump;
  17.         int winnum;
  18.         char winid[10];
  19.  
  20.         winnum =  XtWindow(xwdump);
  21.         
  22.         sprintf(winid,"%d",minnum); /* to convert int into char string */
  23.         execlp("xwd","xwd","-id",winid,"-out","out.xwd",(char *)0);
  24.                    
  25. the xwd gives an error as follows:
  26.              X Error of failed request:  BadWindow (invalid Window parameter)
  27.              Major opcode of failed request:  3 (X_GetWindowAttributes)
  28.              Resource id in failed request:  0x33be198
  29.              Serial number of failed request:  7
  30.              Current serial number in output stream:  7
  31.  
  32.  
  33. but if I note the value of winnum, and type xwd -id winnum -out xwd.out 
  34. on the command line, it works fine. 
  35.  
  36.         Any idea what I'm doing wrong ?
