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.

STANDARDS
     The strcat(), strncat(), strchr(), strrchr(), strcmp(), strncmp(), strcpy(), strncpy(), strerror(), strlen(), strpbrk(), strspn(), strcspn(),
     strstr(), and strtok() functions conform to ISO/IEC 9899:1990 (``ISO C90'').
