DESCRIPTION
The wcpncpy() function is the wide-character equivalent of the stpncpy(3) function. It copies at most n wide characters from the wide-character string pointed to by src, including the terminating null wide (Laq\0aq), 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 Laq\0aq characters. If the length wcslen(src) is greater than or equal to n, the string pointed to by dest will not be Laq\0aq terminated.The strings may not overlap.
The programmer must ensure that there is room for at least n wide characters at dest.
RETURN VALUE
wcpncpy() returns a pointer to the last wide character written, that is, dest+n-1.ATTRIBUTES
