const return values

[DavidA]

Hi

I reported in the Open Discussion forum that I am running TinyXml on a TI DSP. A minor irritation is that the compiler issues a warning for functions such as:
  
   const int IntValue() const; 

The warning is:
  
   "tinyxml\\tinyxml.h", line 698: warning: type qualifier on return type is meaningless
  
I am not a C++ expert and the TI compiler may not be fully compliant, but I wonder if the compiler has a point?  Perhaps const should only be specified
for returned pointers and references?

Fixed, thanks.

Thanks Lee. Here is the complete list of warnings for your consideration:

"tinyxml.h", line 698: warning: type qualifier on return type is meaningless

    const int       IntValue() const;
  
"tinyxml.h", line 699: warning: type qualifier on return type is meaningless

    const double    DoubleValue() const;

"tinyxml.h", line 1210: warning: type qualifier on return type is meaningless

    const int ErrorId()    const        { return errorId; }
 
"tinyxmlparser.cpp", line 1314: warning: variable "tabsize" was set but never used

    int tabsize = 4;
