wmemcpy(3)               Library Functions Manual              wmemcpy(3)

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) 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         top

       wmemcpy() returns dest.
