* stapfuncs.5.in: Document signal.stp tapset functions.
2008-01-16 Eugene Teo <eteo@redhat.com>
* signal.stp (get_sa_flags, get_sa_handler): New functions to
return addresses of sa_flags and sa_handler of struct k_sigaction.
(sigset_mask_str): New function. Returns a string containing the
set of signals to be blocked when executing the signal handler.
(is_sig_blocked): New function. Checks task_struct->blocked signal
mask for signals that are currently blocked.
(signal_str): New function. Translates a signal number.
(sa_flags_str): New function. Translates the sa_flags.
(sa_handler_str): New function. Returns the signal action or handler
associated to the signal.
2008-01-16 Eugene Teo <eteo@redhat.com>
* buildok/signal-embedded.stp: Add all new embedded C functions
in signal.
