The stpncpy
function
shall copy at most n
characters from the string pointed to by src,
including the terminating \0 character, to the array
pointed to by dest. Exactly n
characters are written at dest. If the length
strlen
(src) is smaller than
n, the remaining characters in
dest are filled with \0 characters.
If the length strlen
(src)
is greater than or equal to n,
dest will not be \0 terminated.
The strings may not overlap.
The programmer shall ensure that there is room for at least n characters at dest.
