     strncat(char *s, const char *append, size_t count);

     char *
     strchr(const char *s, int c);

     char *
     strrchr(const char *s, int c);

     int
     strcmp(const char *s1, const char *s2);

     int
     strncmp(const char *s1, const char *s2, size_t count);

     int
     strcoll(const char *s1, const char *s2);

     char *
     strdup(const char *str);

     char *
     strndup(const char *str, size_t len);

     char *
     strstr(const char *big, const char *little);

     char *
     strcasestr(const char *big, const char *little);

     char *
     strtok(char *s, const char *delim);

DESCRIPTION

     The string functions manipulate strings terminated by a nul byte.

     See the specific manual pages for more information.  For manipulating
     variable length generic objects as byte strings (without the nul byte
     check), see bstring(3).

     Except as noted in their specific manual pages, the string functions do
     not test the destination for size limitations.
