DESCRIPTION
The string functions manipulate strings terminated by a null byte.

See the specific manual pages for more information. For manipulating variable length generic objects as byte strings (without the null byte check), see bstring(3).

Except as noted in their specific manual pages, the string functions do not test the destination for size limitations.
