Hallo,

Is not the best thing you can do make an include file with all your constant 
values (also CM_xxx and WM_xxx) for this project, something like in this case:
..
..
#define LEN_MEMUSED  80
..
..

char * memused = (char *)malloc(LEN_MEMUSED);  //allocate 80 bytes
memset(memused, '\0', LEN_MEMUSED );
..
..
and so on
Greetings,
Jan
