Is there a better way?  Or better yet, a proper solution?
Not claiming this is better or proper, just another alternative:


#include <string.h>
size_t ws_strlen(const char *s)
    if (s == NULL)
        return 0;
    return strlen(s);
But this won't work unless we can somehow force vsnprintf() and friends 
to use ws_strlen(). LD_PRELOAD will let you do that [on systems that 
support it], but nobody in their right mind uses LD_PRELOAD for 
production code (I hope).
