wcsncpy — copy a fixed-size string of wide characters
#include <wchar.h>
wchar_t *wcsncpy( |
wchar_t *dest, |
| const wchar_t *src, | |
size_t n); |
The wcsncpy() function is
the wide-character equivalent of the strncpy(3) function. It
copies at most n wide
characters from the wide-character string pointed to by
src, including the
terminating L'\0' character, to the array pointed to by
dest. Exactly
n wide characters are
written at dest. If
the length wcslen(src) is smaller than
n, the remaining wide
characters in the array pointed to by dest are filled with L'\0'
characters. If the length wcslen(src) is greater or
equal to n, the
string pointed to by dest will not be L'\0'
terminated.
The strings may not overlap.
The programmer must ensure that there is room for at least
n wide characters at
dest.
