STRRCHR(3P)                                         POSIX Programmer's Manual                                        STRRCHR(3P)



PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult the corresponding Linux manual page for details of Linux behavior), or the  interface  may  not  be  implemented  on
       Linux.

NAME
       strrchr - string scanning operation

SYNOPSIS
       #include <string.h>

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


DESCRIPTION
       The  strrchr()  function  shall  locate the last occurrence of c (converted to a char) in the string pointed to by s. The
       terminating null byte is considered to be part of the string.

RETURN VALUE
       Upon successful completion, strrchr() shall return a pointer to the byte or a null pointer if c does  not  occur  in  the
       string.

ERRORS
       No errors are defined.

       The following sections are informative.

EXAMPLES
   Finding the Base Name of a File
       The  following  example uses strrchr() to get a pointer to the base name of a file. The strrchr() function searches back-
       wards through the name of the file to find the last '/' character in name. This pointer (plus one) will point to the base
       name of the file.


              #include <string.h>
              ...
              const char *name;
              char *basename;
              ...
              basename = strrchr(name, '/') + 1;
              ...

APPLICATION USAGE
       None.

RATIONALE
       None.

FUTURE DIRECTIONS
