rindex() - locate character in string
#include <strings.h>
char * rindex (const char *s, int c)
The rindex(3) function locates the last character matching c (converted to a char) in the null-terminated string s.
A pointer to the character is returned if it is found; otherwise
NULL is returned. If c is \0,
rindex(3)
locates the terminating \0
.
