Answer / swetcha

Variable-argument functions in C are inherently unsafe
since there is no language-level mechanism to ensure that
the actual arguments agree in type and number with the
arguments that the function will be using. There are
several ways to implement variable argument functions in C

You can try to implement such function by taking the
address of a formal argument and working your way through
the stack frame.A better alternative is to use the
__builtin_next_arg function on gcc and then work your way
up the stack. You can write your variable argument
functions using the standard macros in <stdarg.h> and
<vararg.h>.
