// Get Files and return a table with all files names
void GetFiles(lua_State *lua_state)
{
WIN32_FIND_DATA FindData;
HANDLE FindHandle;
lua_Object tempTable;
int i = 1;
tempTable = lua_createtable(lua_state);
FindHandle = FindFirstFile(luaL_check_string(lua_state,1),&FindData);
if (FindHandle != INVALID_HANDLE_VALUE)
do
{
if (FindData.dwFileAttributes & (FILE_ATTRIBUTE_DIRECTORY |
FILE_ATTRIBUTE_SYSTEM |
FILE_ATTRIBUTE_HIDDEN) )
{
// What do we do with directories etc..
}
else
{
// Add filename to table
lua_pushobject(lua_state,tempTable);
lua_pushnumber(lua_state,i);
i++;
lua_pushstring(lua_state,FindData.cFileName);
lua_settable(lua_state);
}
} while(FindNextFile(FindHandle,&FindData));
FindClose(FindHandle);
lua_pushobject(lua_state,tempTable);
}
Here is a small example of a function that will do what you need (Win32)
