pointer-element-size pointer-or-type => size

pointer-or-type

A FLI pointer to a foreign object or the name of a FLI pointer type.

size

A non-negative integer.

The function pointer-element-size returns the size, in bytes, of the object or type specified.

If pointer-or-type is an FLI pointer, size is the size, in bytes, of the object pointed to by pointer-or-type.

If pointer-or-type is the name of a FLI pointer type, size is the size, in bytes, of the elements of that type.

In the following example a pointer to an integer is created. Then the size in bytes of the integer is returned using pointer-element-size.
