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.

strcspn(), strstr(), and strtok() functions conform to ISO/IEC 9899:1990
(``ISO C90'').
