	Yes.  In C you can do the same:

/* untested code */
...
lua_pushliteral (L, "_TRACEBACK");
lua_rawget(L, LUA_GLOBALSINDEX);  /* get traceback function */
err_func = lua_gettop (L);
/* push function to call */
/* push arguments */
status = lua_pcall (L, <n_args>, <n_results>, err_func);
...

	See the reference manual for details.  And I think the standalone
interpreter is a good example.  If you're calling a C function, there is
lua_cpcall.  Check the manual!

	Hope it will helps,
