The "s" in the name of this function refers to safety,
but safety is a relative term that doesn't always apply to this function.
A more appropriate name for this function would reflect what it does,
which is copying a string with truncation.
Some projects call this function
.BR strtcpy ().
.P
This function is not provided by any libc,
so user-space programmers must implement it themselves.
