SDL - 2 questions

Hi, I would like to ask 2 questions: 1. How can I rotate an image or surface in SDL? 2. How can I get the mouse position during mouse moving in SDL?

Due to some misscommunication pelix and thus pike.ida.liu.se is offline. In all likelyhood it will remain that way until tomorrow morning.

I don't quite understand? In Martin Nilsson's email he stated it should look like below, so `() returns CRCState. Isn't this achieved by inheriting? What do you mean by Clobbering? Isn't by inheriting for every new instance of CRC16 also a new instance of CRCState created? The class CRCState is complete, except for the polynom. Should I create a CRCState object in the _CRC16 class and return it for `() ? class CRC { string name(); int digest_size(); int block_size(); CRCState `() string hash(string data); } class CRCState { string name(); int digest_size(); int block_size(); string hash(string data); CRCState update(string data); string digest(void|int length); }

It doesn't seem to work that way. Attached is the patch to Crypto.pmod/module.pmod (this one is not complete just for testing purpose) If try to use it: >object a = Crypto.CRC16(); /usr/local/pike/7.8.447/lib/modules/Crypto.pmod/module.pmod:118:Illegal program pointer. Compiler Error: 1: Index 'CRC16' not present in module Crypto. Compiler Error: 1: Indexed module was: master()->joinnode(({ /* 1 element */ master()->dirnode("/usr/local/pike/7.8.447/lib/modules/Crypto.pmod":0) })). Compiler Error: 1: Attempt to call a non function value `() (function call). Compiler Error: 1: Expected: function. Compiler Error: 1: Got : zero. If I create a file "CRC16.pmod" like attached in a previous email. I can use CRC16(); > > protected class _MySubModule > { > ... > } > > _MySubModule MySubModule = _MySubModule(); >

Ok. So if I see things right, these mentioned classes should go into "Crypto.pmod/module.pmod" and for each CRC type, I create a module, ie "Crypto.pmod/CRC16X.pmod" ?

I hope this is somewhat in the right direction? What should "digest_size" and "block_size" return? Wouldn't it for the CRC function be better if "digest" and "hash" return the integer value, instead of a string? Best regards, Marc

The hash API basically works looks like this class CRC { string name(); int digest_size(); int block_size(); CRCState `() string hash(string data); } class CRCState { string name(); int digest_size(); int block_size(); string hash(string data); CRCState update(string data); string digest(void|int length); }
