  90. <p><strong>Description</strong><br>
  91. <code>iprintf</code>, <code>fiprintf</code>, <code>siprintf</code>, <code>sniprintf</code>,
  92. <code>asiprintf</code>, and <code>asniprintf</code> are the same as <code>printf</code>,
  93. <code>fprintf</code>, <code>sprintf</code>, <code>snprintf</code>, <code>asprintf</code>, and
  94. <code>asnprintf</code>, respectively, except that they restrict usage
  95. to non-floating-point format specifiers.
  96. </p>
  97. <p><code>_iprintf_r</code>, <code>_fiprintf_r</code>, <code>_asiprintf_r</code>,
  98. <code>_siprintf_r</code>, <code>_sniprintf_r</code>, <code>_asniprintf_r</code> are
  99. simply reentrant versions of the functions above.
  100. </p>
  101. <br>
  102. <p><strong>Returns</strong><br>
  103. Similar to <code>printf</code>, <code>fprintf</code>, <code>sprintf</code>, <code>snprintf</code>, <code>asprintf</code>,
  104. and <code>asnprintf</code>.
  105. </p>
  106. <br>
  107. <p><strong>Portability</strong><br>
  108. <code>iprintf</code>, <code>fiprintf</code>, <code>siprintf</code>, <code>sniprintf</code>, <code>asiprintf</code>,
  109. and <code>asniprintf</code> are newlib extensions.
  110. </p>
  111. <p>Supporting OS subroutines required: <code>close</code>, <code>fstat</code>, <code>isatty</code>,
  112. <code>lseek</code>, <code>read</code>, <code>sbrk</code>, <code>write</code>.
