PROLOG

       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.

NAME

       strrchr — string scanning operation

SYNOPSIS

       #include <string.h>

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

DESCRIPTION

       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.

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  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;
           ...

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
