DESCRIPTION

 The string functions manipulate strings that are 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.
