NAME
    ReadChunkBytes -- Read bytes from the current chunk into a buffer.

SYNOPSIS
    actual = ReadChunkBytes (iff, buf, size)
      d0                     a0   a1    d0

    LONG             actual;
    struct IFFHandle *iff;
    UBYTE            *buf;
    LONG             size;

FUNCTION
    Reads the IFFHandle stream into the buffer for the specified number
    of bytes.  Reads are limited to the size of the current chunk and
    attempts to read past the end of the chunk will truncate.  Function
    returns positive number of bytes read or a negative error code.

INPUTS
    iff     - pointer to IFFHandle struct.
    buf     - pointer to buffer area to receive data.
    size    - number of bytes to read.

RESULT
    actual  - (positive) number of bytes read if successful or a
              (negative) IFFERR_#? error code if not successful.
