   [Solved]Allegro Game taking 300mb of RAM !
  hi guys so i'm making sort of Engine / game kind of thing and i noticed when i open the game it takes about 300MB of RAM !!! WHY ??!!!if i initialize BITMAP a lot does that take from my RAM ?also i dont use destroy BITMAP function does that has to do with the high memory usage ?i know that if you dont destroy bitmap it only takes from the GPU RAM not the main RAMthankx   
  Generally speaking, if you allocate dynamic resources that are intended to be freed, but don't free them, that can cause a memory leak. If you're doing this often (e.g. every frame), then it might result in the kind of memory usage you're seeing.   ;i know that if you dont destroy bitmap it only takes from the GPU RAM not the main RAM[/quote]Not necessarily true. It depends on the exact combination of lower level APIs in use. Also some graphics cards "steal" RAM to use as video memory (though that will probably show up in a different way).;Generally speaking, if you allocate dynamic resources that are intended to be freed, but don't free them, that can cause a memory leak.

And is BITMAP an Allegro type, or something else?   ;how can i free resources?  how can i solve this memory leak ?By pairing a delete[] for every new[], a delete for every new, and a destroy_bitmap for every create_bitmap, load_bitmap, and any other Allegro API function that reminds you "that you are responsible for destroying the bitmap when you are finished with it to avoid memory leaks".   ;[quote name='newbie123' timestamp='1303833642' post='4803115']how can i free resources?It depends on the resource.What language are you programming in?

(There are ways to automate this process, but simply freeing the resource in the destructor would be a good start.)   ;To begin with, if the BITMAP (or a similar resource) is a member of a class, you should free the resource in the destructor for that class.
