       The  functionality  described  on  this  reference  page is aligned with the ISO C standard. Any conflict
       between the requirements described  here  and  the  ISO C  standard  is  unintentional.  This  volume  of
       POSIX.1‐2017 defers to the ISO C standard.

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

       No errors are defined.

FindingtheBaseNameofaFile
       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 '/' 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;
           ...

       None.

       strrchr — string scanning operation

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

       None.

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