I am attempting to process user defaults as prescribed in Adrian Nye's Xlib
Programming Manual Volume One.  Here is the code segment that 
parses the command line into an XrmDatabase structure and attempts to retrieve
the display from the structure:                        


static XrmDatabase commandlineDB;
XrmValue Value;
char *str_typ[20];
static int opTableEntries = 25;
static XrmOptionDescRec opTable[] = {
         .
         .
         .
{"-display", "*display", XrmoptionSepArg, (caddr_t) "NULL"}
         .
         .
         .
};


XrmParseCommand (&commandlineDB, opTable, opTableEntries, argv[0],
                 argc, argv);

if (XrmGetResource (commandlineDB, "m.display", "", str_type, 
                    &value) == True) {
  (void) strncpy (myDisplayName, value.addr, (int) value.size);
}


My application is called m.  What I mean is that the executable looks lik

I call it with -display dkdkdk as the command line arguments.

In the debugger, I can see that argv and argc contain what I expect.

XrmGetResource, however, always returns false no matter what I do.

This must either be because XrmParseCommand is not loading the XrmDatabase
properly or because XrmGetResource is not accessing the XrmDatabase
properly.

Since I do not have the Xrm routines source, I cannot follow this in the 
debugger.   Also, I have had no success at reading the manual about Xrm
and trying various things.

Can anyone spot what is wrong with the above code fragment?


Thanks,
