The strrchr() function returns a pointer to the last occurrence of the character c in the string s. The strchrnul() function is like strchr() except that if c is not found in s, then it returns a pointer to the null byte at the end of s, rather than NULL. Here "character" means "byte"; these functions do not work with wide or multibyte characters. RETURN VALUE The strchr() and strrchr() functions return a pointer to the matched character or NULL if the character is not found. The terminating null byte is considered part of the string, so that if c is specified as '\0', these functions return a pointer to the terminator. The strchrnul() function returns a pointer to the matched character, or a pointer to the null byte at the end of s (i.e., s+strlen(s)) if the character is not found. VERSIONS strchrnul() first appeared in glibc in version 2.1.1.
