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.
