NAME

       hal_add_funct_to_thread - cause a function to be executed at regular intervals

SYNTAX

       int hal_add_funct_to_thread(const char *funct_name, const char *thread_name, int position)

              int hal_del_funct_from_thread(const char *funct_name, const char *thread_name)

ARGUMENTS

       funct_name
              The name of the function.

       thread_name
              The name of the thread.

       position
              The  desired  location  within  the thread.  This determines when the function will
              run, in relation to other functions in the thread.  A positive number indicates the
              desired  location  as  measured from the beginning of the thread, and a negative is
              measured from the end.  So +1 means this function will become the first one to run,
              +5  means it will be the fifth one to run, -2 means it will be next to last, and -1
              means it will be last.  Zero is illegal.

DESCRIPTION

       hal_add_funct_to_thread adds a function exported by a realtime HAL component to a realtime
       thread.  This determines how often and in what order functions are executed.

       hal_del_funct_from_thread removes a function from a thread.

RETURN VALUE

       Returns a HAL status code.

REALTIME CONSIDERATIONS

       Call only from realtime init code, not from other realtime or non-realtime code.
