wmemcpy(3) Library Functions Manual wmemcpy(3)
NAME
wmemcpy - copy an array of wide-characters
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <wchar.h>
wchar_t *wmemcpy(wchar_t dest[restrict .n],
const wchar_t src[restrict .n],
size_t n);
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 char-
acters at dest.
RETURN VALUE
wmemcpy() returns dest.
