STRRCHR(3) BSD Programmer's Manual STRRCHR(3)
strrchr, rindex - locate last occurrence of a character in a string
#include <string.h> char * strrchr(const char *s, int c); char * rindex(const char *s, int c);
The strrchr() function locates the last occurrence of the character c in the string s. The terminating NUL character is considered part of the string. If c is '\0', strrchr() locates the terminating '\0'. The rindex() function is an old synonym for strrchr().
The strrchr() function returns a pointer to the located character or NULL if the character does not appear in the string.
After the following call to strrchr(), p will point to the string "obar": char *p; char *s = "foobar"; p = strrchr(s, 'o');

The strrchr() function conforms to ANSI X3.159-1989 ("ANSI C"). The rindex() function is deprecated and shouldn't be used in new code. MirOS BSD #10-current June 29, 1991 1
