it could not open the file.
The function \verb|lua_dofile|, if called with argument \verb|NULL|,
executes the \verb|stdin| stream.
Function \verb|lua_dofile| is also able to execute pre-compiled chunks.
It automatically detects whether the file is text or binary,
and loads it accordingly (see program \IndexVerb{luac}).
Function \verb|lua_dostring| executes only source code,
and function \verb|lua_dobuffer| executes only pre-compiled chunks.
Functions \verb|lua_dofile| and \verb|lua_dobuffer|
are both able to execute pre-compiled chunks.
They automatically detect whether the chunk is text or binary,
and load it accordingly (see program \IndexVerb{luac}).
Function \verb|lua_dostring| executes only source code.
The third parameter to \verb|lua_dobuffer| (\verb|name|)
is the ``name of the chunk'',
used in error messages and debug information.
In files this name is the file name,
and \verb|lua_dostring| uses a small prefix
of the string as the chunk name.
These functions return, in structure lua2C,
any values eventually returned by the chunks.
