wmemcpy - Man Page

copy an array of wide-characters


#include <wchar.h>

wchar_t *wmemcpy(wchar_t *restrict dest, const wchar_t *restrict src,
                 size_t n);


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.

Return Value

wmemcpy() returns dest.
