<h3 class="section">14.2 Traditional macros, <samp>varargs.h</samp></h3>
|
|
|
|
<p>If your C compiler predates ANSI C, you may still be able to use
|
|
variable argument lists using the macros from the <samp>varargs.h</samp>
|
|
header file. These macros resemble their ANSI counterparts, but have
|
|
important differences in usage. In particular, since traditional C has
|
|
no declaration mechanism for variable argument lists, two additional
|
|
macros are provided simply for the purpose of defining functions with
|
|
variable argument lists.
|
|
</p>
|
|
<p>As with <samp>stdarg.h</samp>, the type <code>va_list</code> is used to hold a data
|
|
structure representing a variable argument list.
|
|
