/*
**  Description:
**  The strlcpy() function copies up to dstsize - 1 characters from the string
**  src to dst, NUL-terminating the result if dstsize is not 0.
**  Room for the NUL-terminator should be included in dstsize.
**
**  Returns:
**  total length of string it tries to create, aka length of src.
