	Backend-private context ptr.

Detailed Description

Opaque handle returned by display_init.

Concrete definition of the opaque handle apps see.

All subsequent PAL calls take a display_handle_t* so the PAL knows which backend to dispatch through. The concrete definition lives in src/ra8_display_pal_internal.h and is invisible to applications.

Since

0.1.0

One module-static instance lives in the dispatcher's TU; the address is returned to callers by display_init. The handle carries the bound iface and the backend's private context pointer – the dispatcher never reaches into ctx itself.

Invariant

iface is non-NULL while the handle is initialised.
