Description
reinterpret_cast reinterprets the bit pattern of a value as an unrelated type, bypassing the type system and often producing implementation-defined or undefined behavior. Prefer a safe alternative (static_cast, std::bit_cast, a proper conversion) or redesign to avoid the cast.
Rationale
reinterpret_cast reinterprets the bit pattern of a value as an unrelated type, bypassing the type system and often producing implementation-defined or undefined behavior. Prefer a safe alternative (static_cast, std::bit_cast, a proper conversion) or redesign to avoid the cast.
The following code illustrates the pattern detected by this rule:
void f() {
// FLAGGED: Use of reinterpret_cast
j = reinterpret_cast<void *>(i);
