int vsnprintf (
/* SYNOPSIS */
char * str,
size_t n,
const char * format,
va_list args)
/* FUNCTION
Format a list of arguments and put them into the string str.
The function makes sure that no more than n characters (including
the terminal 0 byte) are written into str.
INPUTS
str - The formatted result is stored here
n - The size of str
format - A printf() format string.
args - A list of arguments for the format string.
RESULT
The number of characters written into the string. The 0 byte at the
end is not included. If this is greater than or equal to n then
there was not enough room to write all characters. In this case the
output string is not null-terminated, and the return value is the
number of characters which would have been written if enough space had
been available.
