The reader function
lua_Reader()
used by lua_load(3). Every time it needs another piece of
the chunk, lua_load(3) calls the reader, passing along its
data parameter. The reader must return a pointer to a block of memory with a
new piece of the chunk and set size to the block size. The block must exist
until the reader function is called again. To signal the end of the chunk,
the reader must return NULL or set size to zero. The
reader function may return pieces of any size greater than zero.
