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.

SEE ALSO
     bstring(3), index(3), rindex(3), stpcpy(3), strcasecmp(3), strcat(3), strchr(3), strcmp(3), strcpy(3),
     strcspn(3), strerror(3), strlen(3), strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3)

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'').
