In your XmNokCallback routine the call_data parameter returns a pointer 
to the XmFileSelectionBoxCallbackStruct and the "value" member of this 
structure is the filename.  This is how I normally do this.

  void
  send_fselectokCB(w, client_data, sboxstruct)
     Widget w;
     caddr_t client_data;
     XmFileSelectionBoxCallbackStruct *sboxstruct;
  {
     char *string;
  
     XtUnmanageChild(fileselect);
     XtRemoveGrab(fileselect);
  
     string = extractstring(sboxstruct->value);
     free(string);
  }

where extractstring is:

  char
  *extractstring(str)
     XmString str;
  {
     XmStringContext   context;
     XmStringCharSet   charset;
     XmStringDirection direction;
     Boolean           separator;
     static char      *xm_string;
  
     XmStringInitContext (&context, str);
     XmStringGetNextSegment (context, &xm_string, &charset,
                             &direction, &separator);
     XmStringFreeContext (context);
     return ((char *) xm_string);
  }
