#** Updated to Lua 5.1.1 by Bram Kuijvenhoven (bram at kuijvenhoven dot net),
|
||||
#** Hexis BV (http://www.hexis.nl), the Netherlands
|
||||
#** Notes:
|
||||
#** - Only tested with FPC (FreePascal Compiler)
|
||||
#** - Using LuaBinaries styled DLL/SO names, which include version names
|
||||
#** - LUA_YIELD was suffixed by '_' for avoiding name collision
|
||||
#
|
||||
#
|
||||
#** Translated to pascal by Lavergne Thomas
|
||||
#** Notes :
|
||||
#** - Pointers type was prefixed with 'P'
|
||||
#** - lua_upvalueindex constant was transformed to function
|
||||
#** - Some compatibility function was isolated because with it you must have
|
||||
#** lualib.
|
||||
#** - LUA_VERSION was suffixed by '_' for avoiding name collision.
