    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.

    STRING(3)	    UNIX Programmer's Manual		STRING(3)

         Strcmp compares its arguments and returns an integer greater
         than, equal to, or less than 0, according as s1 is lexico-
         graphically greater than, equal to, or less than s2.
         Strncmp makes the same comparison but looks at at most count
         characters.  Strcasecmp and strncasecmp are identical in
         function, but are case insensitive.  The returned lexico-
         graphic 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.
