MISRA.CAST.INT_TO_PTR

Object with integer type or pointer to void cast to pointer type.

MISRA-C++ Rule 5-2-8 (required): An object with integer type or pointer to void type shall not be converted to an object with pointer type.

[Unspecified 5.2.10(7)]

Rationale

In general, converting from an integral type or a pointer to void type to a pointer to an object leads to unspecified behaviour.

Example

struct S
{
   int32_t i;
   int32_t j;
};
void f ( void * v, int32_t i )
{
   S * s1 = reinterpret_cast< S * >( v );   // Non-compliant
   S * s2 = reinterpret_cast< S * >( i );   // Non-compliant
}
