Hello,

I'm trying to use the find algo from the stl library, over a list of
pointers:

std::list<Program *> m_programs

in this method:
Program *GLSLManager::GetProgram(GLhandleARB id)
{
  std::list<Program *>::iterator result;
  result = find(m_programs.begin(), m_programs.end(), id);
  if(result!=m_programs.end())
    return *result;
  else
    return NULL;
}

As far I know I must implement the operator== between the types
GLhandleARB (it is a typedef of ints) and Program * pointers. I do this
by this way:

int operator==(Program *program, GLhandleARB id);  /*it is not a member
of Program class*/

[implementation]
int operator==(Program *program, GLhandleARB id)
{
  return program->GetHandle() == id;
}

but I'm having errors with this:
error C2803: 'operator == must have at least a formal parameter of class
type'

Anyone can help me?

thanks in advance
