strrchr

Defined in header <string.h> 
char *strrchr( const char *str, int ch );
+		 (1) 
/*QChar*/ *strrchr( /*QChar*/ *str, int ch );
+		 (2) (since C23)
+1) Finds the last occurrence of ch (after conversion to char as if by (char)ch) in the null-terminated byte string pointed to by str (each character interpreted as unsigned char). The terminating null character is considered to be a part of the string and can be found if searching for '\0'.
+2) Type-generic function equivalent to (1). Let T be an unqualified character object type. If a macro definition of each of these generic functions is suppressed to access an actual function (e.g. if (strrchr) or a function pointer is used), the actual function declaration (1) becomes visible.

The behavior is undefined if str is not a pointer to a null-terminated byte string.

+

Parameters

+ + +
str - pointer to the null-terminated byte string to be analyzed
ch - character to search for

Return value

Pointer to the found character in str, or null pointer if no such character is found.

+

Example

#include <string.h>
+#include <stdio.h>
+ 
+int main(void)
+{
+    char szSomeFileName[] = "foo/bar/foobar.txt";
+    char *pLastSlash = strrchr(szSomeFileName, '/');
+    char *pszBaseName = pLastSlash ? pLastSlash + 1 : szSomeFileName;
+    printf("Base Name: %s", pszBaseName);
+}

Output:

+
Base Name: foobar.txt
