wmemcpy
(3)copy an array of wide-characters
#include <wchar.h> wchar_t *wmemcpy(wchar_t dest[restrict .n], const wchar_t src[restrict .n], size_t n);
LIBRARY
DESCRIPTION
The wmemcpy() function is the wide-character equivalent of the memcpy(3) 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) to copy between overlapping arrays.
The programmer must ensure that there is room for at least n wide characters at dest.
