strrchr — string scanning operation
Синопсис (Synopsis)
#include <string.h>
char *strrchr(const char *s, int c);
Описание (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.
Возвращаемое значение (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.

Примеры (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;
