<p><strong>Description</strong><br>
|
||
|
|
<code>iprintf</code>, <code>fiprintf</code>, <code>siprintf</code>, <code>sniprintf</code>,
|
||
|
|
<code>asiprintf</code>, and <code>asniprintf</code> are the same as <code>printf</code>,
|
||
|
|
<code>fprintf</code>, <code>sprintf</code>, <code>snprintf</code>, <code>asprintf</code>, and
|
||
|
|
<code>asnprintf</code>, respectively, except that they restrict usage
|
||
|
|
to non-floating-point format specifiers.
|
||
|
|
</p>
|
||
|
|
<p><code>_iprintf_r</code>, <code>_fiprintf_r</code>, <code>_asiprintf_r</code>,
|
||
|
|
<code>_siprintf_r</code>, <code>_sniprintf_r</code>, <code>_asniprintf_r</code> are
|
||
|
|
simply reentrant versions of the functions above.
|
||
|
|
</p>
|
||
|
|
<br>
|
||
|
|
<p><strong>Returns</strong><br>
|
||
|
|
Similar to <code>printf</code>, <code>fprintf</code>, <code>sprintf</code>, <code>snprintf</code>, <code>asprintf</code>,
|
||
|
|
and <code>asnprintf</code>.
|
||
|
|
</p>

|
|
<p><strong>Portability</strong><br>
|
||
|
|
<code>iprintf</code>, <code>fiprintf</code>, <code>siprintf</code>, <code>sniprintf</code>, <code>asiprintf</code>,
|
||
|
|
and <code>asniprintf</code> 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>.
