3.2. Pointer Types

Tilus supports pointer types that represent addresses of data in memory. They are mainly used as parameters of a tilus kernel to accept torch tensors.

The syntax to define a pointer type is as follows:

~<dtype>

Where dtype is one of the scalar types (e.g., float32) in Scalar Types, or a pointer type itself.

Pointer to Scalar We can define a pointer to a scalar type like ~float32.

Pointer to Pointer We can also define a pointer to another pointer type, like ~(~float32)) to represent a pointer to a pointer to a 32-bit float type.

Void Pointer A special pointer type tilus.ir.void_p, which represents a pointer to an unspecified data type, is often used as a generic pointer type.
