int and long are different types, according to C++. The fact they have the same representation on a given platform does not matter. Accessing an object of type T1 through a pointer of type T2 (with T1 and T2 unrelated, and with the exception of T2=char) is invalid as per the aliasing rules specified in the ISO C++ standard. Modern compilers exploit this: if they see a long* and an object of type int, they can assume that the long* will never point to the int object, and thus will not be able to modify its contents in any way. This is off-topic though :) -- Giovanni Bajo _______________________________________________ PyKDE mailing list PyKDE@mats.imk.fraunhofer.de http://mats.imk.fraunhofer.de/mailman/listinfo/pykde
