strrchr

The strrchr function scans a string backwards for the last occurrence of a given

character.

str_ptr

points to the string to scan.

chr

is the character to scan for.

Return Value

points to the last occurrence in *str_ptr of the character chr. If *str_ptr does not

contain chr, then strrchr returns the pointer value NULL.

Example

This example searches string s for the character “a” and prints the character:

#include <stringh>

#include <stdioh>

int main(void)

{

char *p;

char *s;

int c;

c = 'a';

s = "This is an example";

p = strrchr(s, c);

printf("%c", *p);

}

#include <stringh>

char *strrchr(const char *str_ptr, int chr);
