a FLI type specifying the type of the object to be allocated. If type is supplied, pointer-type must not be supplied.
A FLI pointer type specifying the type of the pointer object to be allocated. If pointer-type is supplied, type must not be supplied.
A keyword setting the initial value of every element in the newly allocated object to initial-element .
A list of forms which initialize the contents of each element in the newly allocated object.
An integer between 0 to 255.
An integer specifying how many copies of the object should be allocated. The default value is 1.
A symbol naming a slot in the object.
allocates memory for a new instance of an object of type
or an instance of a pointer object of type
. Memory allocated in this manner must be explicitly freed using
once the object is no longer needed.
A supplied value of size-slot applies if the type is a struct or union type. The slot size-slot is set to the size of the object in bytes. This occurs after the fill , initial-element and initial-contents arguments are processed. If nelems is greater than 1, then the slot size-slot is initialized in each element. If size-slot is not supplied, then no such setting occurs.
In the following example a structure is defined and an instance with a specified initial value of 10 is created with memory allocated using
. The dereference function is then used to get the value that
points to, and finally it is freed.
