    NAME

    
    
    index , rindex
    
     - locate character in string
    
     
    

    LIBRARY

    Lb libc
    
     
    

    SYNOPSIS

       #include <strings.h>
    char * index (const char *s int c);
    char * rindex (const char *s int c);
     

    DESCRIPTION

    The index ();
    function locates the first occurrence of Fa c (converted to a Vt char ) in the string pointed to by Fa s . The terminating null character is considered part of the string; therefore if Fa c is `\0' , the functions locate the terminating `\0'

    The rindex ();
    function is identical to index (,);
    except it locates the last occurrence of Fa c .  

    RETURN VALUES

    The functions index ();
    and rindex ();
    return a pointer to the located character, or NULL if the character does not appear in the string.  

    SEE ALSO

    memchr(3), strchr(3), strcspn(3), strpbrk(3), strrchr(3), strsep(3), strspn(3), strstr(3), strtok(3)  

    HISTORY

    The index ();
    and rindex ();
    functions appeared in AT&T System v6 . Their prototypes existed previously in    #include <string.h>
    before they were moved to    #include <strings.h>
    for St -p1003.1-2001 compliance.
