16 The wcpncpy() function is the wide-character equivalent of the stp‐
17 ncpy() function. It copies at most n wide characters from the wide-
18 character string pointed to by src, including the terminating L'\0'
19 character, to the array pointed to by dest. Exactly n wide characters
20 are written at dest. If the length wcslen(src) is smaller than n, the
21 remaining wide characters in the array pointed to by dest are filled
22 with L'\0' characters. If the length wcslen(src) is greater or equal to
23 n, the string pointed to by dest will not be L'\0' terminated.
24
25 The strings may not overlap.
26
27 The programmer must ensure that there is room for at least n wide char‐
28 acters at dest.
29
31 wcpncpy() returns a pointer to the last wide character written, i.e.
32 dest + n - 1.

35 This function is a GNU extension.
