parse_chunk_size()

static apr_status_t parse_chunk_size ( http_ctx_t *  ctx, const char *  buffer, apr_size_t  len, int  linelimit, int  strict  )

static

Parse a chunk line with optional extension, detect overflow. There are several error cases: 1) If the chunk link is misformatted, APR_EINVAL is returned. 2) If the conversion would require too many bits, APR_EGENERAL is returned. 3) If the conversion used the correct number of bits, but an overflow caused only the sign bit to flip, then APR_ENOSPC is returned. A negative chunk length always indicates an overflow error.
