NAME
       byte_rchr - search for a byte in a string

SYNTAX
       #include <byte.h>

       size_t byte_rchr(const char *haystack,size_t len,char needle);

DESCRIPTION
       byte_chr returns the largest integer i between 0 and len-1 inclusive
       such that one[i] equals needle.

       If no such integer exists, byte_chr returns len.

       byte_rchr may read all bytes one[0], one[1], ..., one[len-1], even if
       not all the bytes are relevant to the answer.
