» HAL entry points from RISC OS (index by function)

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

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).
