HAL entry points by number

Hardware Abstraction Layer

» HAL entry points from RISC OS

» Index by number

These are the entry points into the HAL, called directly from the OS or via SWI OS_Hardware, indexed by number.

Items marked ¶ are internal calls for OS use only; their functionality and availability is subject to change without warning. User programs interested in using these calls should instead use the equivalent RISC OS SWI call (if available).
