Type Definition linuxcnc_hal_sys::hal_type_t

type hal_type_t = i32;

HAL pins and signals are typed, and the HAL only allows pins to be attached to signals of the same type. All HAL types can be read or written atomically. (Read-modify- write operations are not atomic.) Note that when a component reads or writes one of its pins, it is actually reading or writing the signal linked to that pin, by way of the pointer. 'hal_type_t' is an enum used to identify the type of a pin, signal, or parameter.
