.Sh DESCRIPTION
|
|
The string
|
|
functions manipulate strings terminated by a
|
|
null byte.
|
|
.Pp
|
|
See the specific manual pages for more information.
|
|
For manipulating variable length generic objects as byte
|
|
strings (without the null byte check), see
|
|
.Xr bstring 3 .
|
|
.Pp
|
|
Except as noted in their specific manual pages,
|
|
the string functions do not test the destination
|
|
for size limitations.
