strlcpy - Copy a NUL terminated string into a sized buffer
size_t strlcpy (char * dest, const char * src, size_t size);
dest Where to copy the string to src Where to copy the string from size size of destination buffer
the result is always a valid NUL-terminated string that fits in the buffer (unless, of course, the buffer size is zero). It does not pad out the result like strncpy does.
