wmemcpy - copy an array of wide-characters
Standard C library (libc
, -lc
)
#include <wchar.h>
wchar_t *wmemcpy(wchar_t dest[restrict .n],
const wchar_t src[restrict .n],
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
.
wmemcpy() returns dest
.
