wcpncpy
is the wide-character equivalent of
stpncpy
. It copies at most n
wide characters from the wide-character string src,
including the terminating L'\0' character, to the
array 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 dest are filled
with L'\0' characters. If the length
wcslen
(src) is greater
than or equal to n, the string
dest will not be L'\0'
terminated.
The strings may not overlap.
The programmer shall ensure that there is room for at least n wide characters at dest.
