The C standard also allows to use memcpy to do type punning:

    If a value is copied into an object having no declared type using memcpy or memmove,
    or is copied as an array of character type, then the effective type of the modified
    object for that access and for subsequent accesses that do not modify the value is
    the effective type of the object from which the value is copied, if it has one

Simply memcpy into a variable (as opposed to dynamically allocated memory).
