  55. <p><strong>Synopsis</strong>
  56. </p><div class="example">
  57. <pre class="example">#include &lt;wchar.h&gt;
  58. wchar_t *wmemcpy(wchar_t *__restrict <var>d</var>,

  61. <p><strong>Description</strong><br>
  62. The <code>wmemcpy</code> function copies <var>n</var> wide characters from the object
  63. pointed to by <var>s</var> to the object pointed to be <var>d</var>. This function
  64. is not affected by locale and all wchar_t values are treated
  65. identically. The null wide character and wchar_t values not
  66. corresponding to valid characters are not treated specially.
  67. </p>
  68. <p>If <var>n</var> is zero, <var>d</var> and <var>s</var> must be a valid pointers, and the
  69. function copies zero wide characters.
  70. </p>
  71. <br>
  72. <p><strong>Returns</strong><br>
  73. The <code>wmemcpy</code> function returns the value of <var>d</var>.
  74. </p>
  75. <br>
  76. <p><strong>Portability</strong><br>
  77. <code>wmemcpy</code> is ISO/IEC 9899/AMD1:1995 (ISO C).
