NAME top

   wmemcpy - copy an array of wide-characters

LIBRARY top

   Standard C library (_libc_, _-lc_)

SYNOPSIS top

   **#include <wchar.h>**

   **wchar_t *wmemcpy(wchar_t** _dest_**[restrict .**_n_**],**
                    **const wchar_t** _src_**[restrict .**_n_**],**
                    **size_t** _n_**);**

DESCRIPTION top

   The **wmemcpy**() function is the wide-character equivalent of the
   [memcpy(3)](../man3/memcpy.3.html) function.  It copies _n_ wide characters from the array
   starting at _src_ to the array starting at _dest_.

   The arrays may not overlap; use [wmemmove(3)](../man3/wmemmove.3.html) to copy between
   overlapping arrays.

   The programmer must ensure that there is room for at least _n_ wide
   characters at _dest_.

RETURN VALUE top

   **wmemcpy**() returns _dest_.
