rtapi_init3rtapi

Usage

Arguments

modname

The name of this rtapi module

Overview

rtapi_init sets up the RTAPI. It must be called by any module that intends to use the API, before any other RTAPI calls.

modname can optionally point to a string that identifies the module. The string will be truncated at RTAPI_NAME_LEN characters. If modname is NULL, the system will assign a name.

Realtime considerations

Call only from within non-realtime or realtime init/cleanup code, not from relatime tasks.

Return value

On success, returns a positive integer module ID, which is used for subsequent calls to rtapi_xxx_new, rtapi_xxx_delete, and rtapi_exit. On failure, returns an RTAPI error code.
