pub unsafe extern "C" fn lua_load(

Expand description

[-0, +1, -] Loads a Lua chunk. If there are no errors, lua_load pushes the compiled chunk as a Lua function on top of the stack. Otherwise, it pushes an error message. The return values of lua_load are:

  • 0: no errors;
  • LUA_ERRSYNTAX: syntax error during pre-compilation;
  • LUA_ERRMEM: memory allocation error. This function only loads a chunk; it does not run it.

lua_load automatically detects whether the chunk is text or binary, and loads it accordingly (see program luac).

The lua_load function uses a user-supplied reader function to read the chunk (see lua_Reader). The data argument is an opaque value passed to the reader function.

The chunkname argument gives a name to the chunk, which is used for error messages and in debug information
