This function is similar to @code{sprintf}, but it will write to@var{buf} at most @code{@var{n}-1} bytes of text, followed by aterminating null byte, for a total of @var{n} bytes.On error the return value is -1, otherwise it returns the number ofbytes, not including the terminating null byte, that would have beenwritten had @var{n} been sufficiently large, regardless of the actualvalue of @var{n}.  Note some pre-C99 system libraries do not implementthis correctly so users cannot generally rely on the return value ifthe system version of this function is used. @end deftypefn */ #include "ansidecl.h" #include <stdarg.h>#include <stddef.h> int vsnprintf (char *, size_t, const char *, va_list); intsnprintf (char *s, size_t n, const char *format, ...){  int result;  va_list ap;  va_start (ap, format);  result = vsnprintf (s, n, format, ap);  va_end (ap);  return result;}
