Overview
hal_init sets up HAL and RTAPI. It must be called by any module that intends to use the API, before any other RTAPI calls.
modname must point to a string that identifies the module. The string may be no longer than HAL_NAME_LEN characters.
Realtime considerations
Call only from within non-realtime or init/cleanup code, not from realtime tasks.
Return value
On success, returns a positive integer module ID, which is used for subsequent calls to HAL and rtapi APIs. On failure, returns a HAL error code.
