<body>
  <p>DR 497 Proposed Technical Corrigendum</p>

  <p>In 7.1.1, add a new paragraph:</p>

  <blockquote>
    In this clause, references to "white-space character" refer to
    (execution) white-space character as defined by
    <b>isspace()</b>. References to "white-space wide character"
    refer to (execution) white-space wide character as defined by
    <b>iswspace()</b>.
  </blockquote>

  <p>Remove '(as specified by the <b>isspace</b> function)' in:
  7.21.6.2#8 (fscanf), 7.22.1.3#2 (strtod), 7.22.1.4#2
  (strtol).</p>

  <p>Remove '(as specified by the <b>iswspace</b> function)' in:
  7.29.2.2#8 (fwscanf), 7.29.4.1.1#2 (wcstod), 7.29.4.1.2#2
  (wcstol).</p>

  <p>Change "white space" to "white-space characters": 7.21.6.2#15
  (fscanf), 7.22.1.4#4 (strtol).</p>

  <p>Change "white space" to "white-space wide characters":
  7.29.2.2#15 (fwscanf), 7.29.4.1.2#4 (wcstol).</p>

  <p>In <b>7.4.1.10 The isspace function</b> paragraph 2,
  change:</p>

  <blockquote>
    The <b>isspace</b> function tests for any character that is a
    standard white-space character or is one of a locale-specific
    set of characters for which <b>isalnum</b> is false.
  </blockquote>

  <p>to:</p>

  <blockquote>
    The <b>isspace</b> function tests for any character that is a
    standard white-space character or is one of a locale-specific
    set of characters for which none of <b>isalnum</b>,
    <b>iscntrl</b>, and <b>ispunct</b> are true.
  </blockquote>

  <p>In <b>7.30.2.1.10 The iswspace function</b> paragraph 2,
  change:</p>

  <blockquote>
    The <b>iswspace</b> function tests for any wide character that
    corresponds to a locale-specific set of white-space wide
    characters for which none of <b>iswalnum</b>, <b>iswgraph</b>,
    or <b>iswpunct</b> is true.
  </blockquote>

  <p>to:</p>

  <blockquote>
    The <b>iswspace</b> function tests for any wide character that
    corresponds to a locale-specific set of white-space wide
    characters for which none of <b>iswalnum</b>, <b>iswcntrl</b>,
    or <b>iswpunct</b> is true.
  </blockquote>

  <p>Add "white-space wide character" to the index.</p>
