PROLOG

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

NAME

13       strrchr — string scanning operation
14

SYNOPSIS

16       #include <string.h>
17
18       char *strrchr(const char *s, int c);
19

DESCRIPTION

21       The functionality described on this reference page is aligned with  the
22       ISO C  standard.  Any  conflict between the requirements described here
23       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
24       defers to the ISO C standard.
25
26       The strrchr() function shall locate the last occurrence of c (converted
27       to a char) in the string pointed to by s.  The terminating NUL  charac‐
28       ter is considered to be part of the string.
29

RETURN VALUE

31       Upon  successful  completion,  strrchr()  shall return a pointer to the
32       byte or a null pointer if c does not occur in the string.
33

ERRORS

35       No errors are defined.

EXAMPLES

40   Finding the Base Name of a File
41       The following example uses strrchr() to get a pointer to the base  name
42       of  a  file. The strrchr() function searches backwards through the name
43       of the file to find the last '/' character in name.  This pointer (plus
44       one) will point to the base name of the file.

46           #include <string.h>
47           ...
48           const char *name;
49           char *basename;
50           ...
51           basename = strrchr(name, '/') + 1;
52           ...
