NAME
       strcat, strncat, strcmp, strncmp, strcasecmp, strncasecmp, strcpy, strncpy, strlen, index,
       rindex - string operations

SYNOPSIS
       #include <strings.h>

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

       char *strncat(s, append, count)
       char *s, *append;
       int count;

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

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

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

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

       char *strcpy(to, from)
       char *to, *from;

       char *strncpy(to, from, count)
       char *to, *from;
       int count;

       strlen(s)
       char *s;

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

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

DESCRIPTION
       These functions operate on null-terminated strings.  They do not check for overflow of any
       receiving string.

       Strcat  appends	a  copy  of  string append to the end of string s. Strncat copies at most
       count characters.  Both return a pointer to the null-terminated result.

       Strcmp compares its arguments and returns an integer greater than, equal to, or less  than
       0,  according as s1 is lexicographically greater than, equal to, or less than s2.  Strncmp
       makes the same comparison but looks at at most count  characters.   Strcasecmp  and  strn-
       casecmp	are  identical in function, but are case insensitive.  The returned lexicographic
       difference reflects a conversion to lower-case.

       Strcpy copies string from to to,  stopping  after  the  null  character	has  been  moved.
       Strncpy	copies exactly count characters, appending nulls if from is less than count char-
       acters in length; the target may not be null-terminated if the length of from is count  or
       more.  Both return to.

       Strlen returns the number of non-null characters in s.

       Index (rindex) returns a pointer to the first (last) occurrence of character c in string s
       or zero if c does not occur in the string.  Setting c to NULL works.
