NAME

       rtapi_app_main - User-provided function to initialize a component

SYNTAX

       #include <rtapi_app.h>

       int rtapi_app_main(void) {...}

ARGUMENTS

       None

DESCRIPTION

       The  body  of  rtapi_app_main, which is provided by the component author, generally consists of a call to
       rtapi_init or hal_init, followed by other component-specific initialization code.

RETURN VALUE

       Return 0 for success.  Return a negative errno value  (e.g.,  -EINVAL)  on  error.   Existing  code  also
       returns RTAPI or HAL error values, but using negative errno values gives better diagnostics from insmod.

REALTIME CONSIDERATIONS

       Called automatically by the rtapi infrastructure in an initialization (not realtime) context.
