strrchr - string scanning operation
#include "zkString.h"
char *strrchr(const char *s, int c);
The strrchr() function locates the last occurrence of c (converted to a char) in the string pointed to by s. The terminating null byte is considered to be part of the string.
Upon successful completion, strrchr() returns a pointer to the byte or NULL if c does not occur in the string.
