const member functions detection

[dcb]

For this C++ source code:

class S
{
private:
int fred;

public:
S( int n) : fred( n) { };
~S() {};

int getFred() { return fred; };

};

where the member function body is only a return statement and so the member
function could be made const, cppcheck doesn't detect this situation.

$ /home/dcb/cppcheck/trunk/cppcheck --enable=all may8e.cc
may8e.cc:14:0: style: The function 'getFred' is never used. [unusedFunction]
$

I am not sure if this is a feature request or a bug report.

can you try with inconclusive also.

The warning is inconclusive because there can be situations when a method could technically be const, but for design reasons you would like that it is not.

It works fine with --inconclusive flag.

$ /home/dcb/cppcheck/trunk/cppcheck --enable=all --inconclusive may8e.cc
may8e.cc:14:6: style:inconclusive: Technically the member function 'S::getFred' can be const. [functionConst]
int getFred() { return fred; };
^
may8e.cc:14:0: style: The function 'getFred' is never used. [unusedFunction]

Fast work. Thanks very much for your help.
