  1. /*
  2. FUNCTION
  3.         <<wmemcpy>>---copy wide characters in memory
  4.  
  5. ANSI_SYNOPSIS
  6.         #include <wchar.h>
  7.         wchar_t *wmemcpy(wchar_t *__restrict <[d]>,
  8.                          const wchar_t *__restrict <[s]>, size_t <[n]>);
  9.  
  10. TRAD_SYNOPSIS
  11.         wchar_t *wmemcpy(<[d]>, <[s]>, <[n]>
  12.         wchar_t *__restrict <[d]>;
  13.         const wchar_t *__restrict <[s]>;
  14.         size_t <[n]>;
  15.  
  16. DESCRIPTION
  17.         The <<wmemcpy>> function copies <[n]> wide characters from the object
  18.         pointed to by <[s]> to the object pointed to be <[d]>. This function
  19.         is not affected by locale and all wchar_t values are treated
  20.         identically.  The null wide character and wchar_t values not
  21.         corresponding to valid characters are not treated specially.
  22.  
  23.         If <[n]> is zero, <[d]> and <[s]> must be a valid pointers, and the
  24.         function copies zero wide characters.
  25.  
  26. RETURNS
  27.         The <<wmemcpy>> function returns the value of <[d]>.
  28.  
  29. PORTABILITY
  30. <<wmemcpy>> is ISO/IEC 9899/AMD1:1995 (ISO C).
  31.  
  32. No supporting OS subroutines are required.
