STRRCHR(3P) POSIX Programmer's Manual STRRCHR(3P)
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.
strrchr — string scanning operation
#include <string.h>
char *strrchr(const char *s, int c);
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.1‐2008 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.
Upon successful completion, strrchr() shall return a pointer to the
byte or a null pointer if c does not occur in the string.
No errors are defined.
The following sections are informative.
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;
...
None.
None.
None.
