  2. FUNCTION
  3.         <<wmemmove>>---copy wide characters in memory with overlapping areas
  4.  
  5. ANSI_SYNOPSIS
  6.         #include <wchar.h>
  7.         wchar_t *wmemmove(wchar_t *<[d]>, const wchar_t *<[s]>, size_t <[n]>);
  8.  
  9. TRAD_SYNOPSIS
  10.         wchar_t *wmemmove(<[d]>, <[s]>, <[n]>
  11.         wchar_t *<[d]>;
  12.         const wchar_t *<[s]>;
  13.         size_t <[n]>;
  14.  
  15. DESCRIPTION
  16.         The <<wmemmove>> function copies <[n]> wide characters from the object
  17.         pointed to by <[s]> to the object pointed to by <[d]>. Copying takes
  18.         place as if the <[n]> wide characters from the object pointed to by
  19.         <[s]> are first copied into a temporary array of <[n]> wide characters
  20.         that does not overlap the objects pointed to by <[d]> or <[s]>, and then
  21.         the <[n]> wide characters from the temporary array are copied into the
  22.         object pointed to by <[d]>.
  23.  
  24.         This function is not affected by locale and all wchar_t values are
  25.         treated identically. The null wide character and wchar_t values not
  26.         corresponding to valid characters are not treated specially.
  27.  
  28.         If <[n]> is zero, <[d]> and <[s]> must be a valid pointers, and the
  29.         function copies zero wide characters.
  30.  
  31. RETURNS
  32.         The <<wmemmove>> function returns the value of <[d]>.
  33.  
  34. PORTABILITY
  35. <<wmemmove>> is ISO/IEC 9899/AMD1:1995 (ISO C).
  36.  
  37. No supporting OS subroutines are required.
