how I would rewrite the pseudocode from http://www.cocos2d-x.org/boards/6/topics/16774

gistfile1.cpp

bool foo(char* p1, int* p2)
{
    // local variable declaration
    bool bRet = false;  // init all local variables here, assume everything is wrong
    int*  ptr = NULL;

    PROFILER_START();

    // check input params
    if (p1 && p2)
    {
        // start our affairs
	      if (createSomething() && initSomething())
 	      {
		      if (cond)
		      {
		          ptr = (int*)mallc(123123243);  
		      }
		      bRet = (ptr && doSomething(ptr));
 	      }
    }

    // start clean up phase
    if (ptr)     
    {
        delete ptr;
        ptr = NULL;
    }

    if (!bRet)
    {
        reserveSomething();
    }

    // So we haven't missed anything until here.
    // Make sure the local variables are cleaned, especially the pointer's are deleted.
    // A function should have only one return point! 
    // In this way, it's very easy to add profiler into each function, only one line at start and one at the end.
    PROFILER_STOP();
    return bRet;
}
