The rsize argument holds the actual length of what was decoded.
You have to limit printf by that size.

A rough flow of my program(in pseudo C code):

rv = read(sock, buf, 4096);
phr_parse_response(...); /* I check the headers after this and set chunked_response = 1 if headers indicate */
if (chunked_response) {
    size = rv /* setting this to offset buffer with what has been read so far */
    do {
        while ((rret = read(sock, buf + size, capacity - size)) == -1 && errno == EINTR)
            ;
        if (rret <= 0)
            return IOError;
        /* decode */
        rsize = rret;
        pret = phr_decode_chunked(&decoder, buf + size, &rsize);
        if (pret == -1)
            return ParseError;
        size += rsize;
    } while (pret == -2);
}
printf("%s", buf); /* prints the output shown above */

I am adding rsize of each decode to size. So I should limit it by size to print the whole buffer?

I would guess so, yes.
Where i am using it i simply cut off the buffer each time i use phr_decode_chunked.

Thanks. When I limit the printf by the size, it prints the decoded chunks correctly.
