that code snippet has been taken from an IRIX w/s.
#if defined(_ANSI_NULL_POINTER) && defined(__STDC__)
#define NULL ((void *)0L)
#else
#define NULL 0L
#endif
agree for the benefit of the OP we should take it offline ;)
btw i replied to your PM so whenever you get a chance...
agree that long int 0L by itself is not a pointer and by the same argument neither is int 0L unless cast.
imo only difference is the precision and pedantic in this context refers purely to the...
and why not? go figure :D
Correct as the NULL symbol can be redefined elsewhere thereby taking precedence over its definition in the C library include files.
I concur
#define NULL ((void *)0L) now that's pedantic :D
IMHO that would be decided internally by the machine's native character set ie ASCII or EBCDIC instead of by the compiler.
Look at the memset() call to initialize the array of task structs or a particular element thereof to NULL.
