SYNOPSIS

     #include <string.h>

     char *
     strcat(char *s, const char * append);

     char *
     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
     strcasecmp(const char *s1, const char *s2);

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

     char *
     strcpy(char *dst, const char *src);

     char *
     strncpy(char *dst, const char *src, size_t count);

     char *
     strerror(int errno);

     size_t
     strlen(const char *s);

     char *
     strpbrk(const char *s, const char *charset);

     char *
     strsep(char **stringp, const char *delim);

     size_t
     strspn(const char *s, const char *charset);

     size_t
     strcspn(const char *s, const char *charset);

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

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

     char *
     strtok_r(char *s, const char *delim, char **lasts);

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

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


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(), strsep(), strspn(),
     strcspn(), strstr(), and strtok() functions conform to ANSI X3.159-1989
     (``ANSI C'').  The strtok_r() function conforms to IEEE Std 1003.1c-1995
     (``POSIX.1'').
