BS>  Okay, and with pointers it's NULL.

    NULL is defined by implementation, but it is usually 0.  This
 bit here is from the stddef.h file for MSVC5.0.

MSVC-stddef.h>   #ifndef NULL
MSVC-stddef.h>   #ifdef __cplusplus
MSVC-stddef.h>   #define NULL 0
MSVC-stddef.h>   #else
MSVC-stddef.h>   #define NULL ((void *)0)
MSVC-stddef.h>   #endif
MSVC-stddef.h>   #endif

    The inclusion of the NULL macro in stddef.h is part of the
 standard, so it is easy to check your compiler to see if NULL is
 equal to zero.  It should be, but the standard does not specify
 that it is.  If you are faced with an unknown compiler, you can
 just look at stddef.h to see, or you can run a bit of code to
 find out.

/*   seenull.c  Public Domain test of the value of NULL   */
#include 
int main (void)
{
    char* test = NULL, buf[16];
    printf("test = %p.\n", test);
    fgets(buf, 16, stdin);
    return 0;
}
