In python (and probably some other softwares), it is using function pointer casting to store the python method function pointers. This sometimes forcely changed the signature of the function. One example is dict_keys function, which has the signature of PyObject *dict_keys(PyDictObject *mp)....
Casting to char, incrementing by x, and then reinterpreting the new value as some other type is both pointless and undefined behaviour. – underscore_d Aug 20 at 6:32 add a commentup vote 6 down vote You have to cast it to another type of pointer before doing pointer arithmetic. ...
Integer-Pointer CastingSeparation LogicVerificationAlthough there have been many approaches for developing formal memory models that support integer-pointer casts, previous approaches share the drawback that they are not designed for end-to-end verification, failing to support some important source-level ...
Final conclusion: arithmetic on a void* is illegal in both C and C++. GCC allows it as an extension, seeArithmetic on void- and Function-Pointers(note that this section is part of the "C Extensions" chapter of the manual). Clang and ICC likely allow void* arithmetic for the purposes of...
How do I convert/cast a C_PRT pointer into a HANDLE? The TRANSFER instrinsic function does not work here. Please help! Translate 0 Kudos Copy link Reply Steven_L_Intel1 Employee 09-12-2013 05:03 PM 659 Views See your other thread. TRANSFER works just...
It is UB in C and C++ to type-pun pointers in this way, for two reasons. First, casting to a pointer is forbidden if the pointer is not aligned. Second, this kind of type-punning is a strict aliasi...
Implicit Casting and Bridging When calling a function or method with anUnsafeMutablePointerparameter, you can pass an instance of that specific pointer type or use Swift’s implicit bridging to pass a compatible pointer. For example, theprintInt(atAddress:)function in the following code sample exp...
in the code you posted: uintvar1 and uintvar2(3) Since you haven't shown what you want to do with the pointers, we can't say if it will "work" or not.If you mean assigning a pointer to one type of int to a pointer to anther type of int with casting, well ... it should ...
When the item type was a menu, the initializations and moving of that pointer address to current_menu didn't require any type-casting. The problem came when trying to call a function pointer with the item, and I still think it was probably just a syntax issue on my side. By changing ...
C-style cast works like static_, const and reinterpret cast at once. And you cannot be sure that types you casting between are compatible. So do not use C-style casts in C++ EDIT: As I mentioned earlier it is a C-function. In C++ it would be better to use templates for that. ...
