Cleaning operation #64

In libtwolame/mem.h I see the macro (useful, indeed) TWOLAME_FREE which is defined as follows: if(ptr!=NULL) { free(ptr); ptr=NULL; } Now, what's the point in setting to NULL a parameter passed as value? The caller will never see the change. I don't get this.

Oh, got it! It's a macro, not a function. Sorry.
