<p><strong>Description</strong><br>
|
|
<code>viprintf</code>, <code>vfiprintf</code>, <code>vasiprintf</code>, <code>vsiprintf</code>,
|
|
<code>vsniprintf</code>, and <code>vasniprintf</code> are (respectively) variants of
|
|
<code>iprintf</code>, <code>fiprintf</code>, <code>asiprintf</code>, <code>siprintf</code>, <code>sniprintf</code>,
|
|
and <code>asniprintf</code>. They differ only in allowing their caller to pass
|
|
the variable argument list as a <code>va_list</code> object (initialized by
|
|
<code>va_start</code>) rather than directly accepting a variable number of
|
|
arguments. The caller is responsible for calling <code>va_end</code>.
|
|
</p>
|
|
<p><code>_viprintf_r</code>, <code>_vfiprintf_r</code>, <code>_vasiprintf_r</code>,
|
|
<code>_vsiprintf_r</code>, <code>_vsniprintf_r</code>, and <code>_vasniprintf_r</code> are
|
|
reentrant versions of the above.
|
|
</p>
|
|
<br>
|
|
<p><strong>Returns</strong><br>
|
|
The return values are consistent with the corresponding functions:
|
|
</p>
|
|
<br>
|
|
<p><strong>Portability</strong><br>
|
|
All of these functions are newlib extensions.
|
|
</p>
|
|
<p>Supporting OS subroutines required: <code>close</code>, <code>fstat</code>, <code>isatty</code>,
|
|
<code>lseek</code>, <code>read</code>, <code>sbrk</code>, <code>write</code>.
