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.

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 backwards through the name of the file to find the
       last â€â€™/â€â€™ 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, â€â€™/â€â€™) + 1;
              ...

APPLICATION USAGE
