Description

The unary (*) operator denotes indirection. If the operand points to an object, the result is an l-value designating the object. If the operand has type "pointer to type", the result has type "type". If an invalid value has been assigned to the pointer, the behavior of the unary * operator is undefined [1].

1. Among the invalid values for dereferencing a pointer by the unary * operator are a null pointer, an address inappropriately aligned for the type of object pointed to, and the address of an object after the end of its lifetime. If *P is an l-value and T is the name of an object pointer type, *(T)P is an l-value that has a type compatible with that to which T points.
