| 44 | // How does this work? |
|---|
| 45 | // Remember that before the compiler starts to process a source file, it runs |
|---|
| 46 | // a neat tool called a preprocessor on it. What this preprocessor does in |
|---|
| 47 | // this case is replace all the instances of *alloc/free with the expanded |
|---|
| 48 | // macros - this way we cleverly replace all the calls to the standard C |
|---|
| 49 | // memory (de)allocation functions. The same is done for new/delete |
|---|
| 50 | // |
|---|
| 51 | // Of course, we have the drawback that we can't name a member function of |
|---|
| 52 | // a class *alloc or free and we can't overload the new/delete operators without |
|---|
| 53 | // first undefining these macros - ah, a C++ preprocessor with RE replacement, |
|---|
| 54 | // that would be a dream come true :) |
