From the SUSv3 System Interfaces volume (excuse the bad formatting):
41429 The structure sigaction, used to describe an action to be taken,
is defined in the <signal.h>
41430 header to include at least the following members:
41431
41432 Member Type Member Name Description
41433 void(*) (int) sa_handler SIG_DFL, SIG_IGN, or pointer to a
function.
43434 sigset_t sa_mask Additional set of signals to be
blocked during execution of
signal-catching function.
41437 int sa_flags Special flags to affect behavior of
signal.
41438 void(*) (int,
41439 siginfo_t *, void *) sa_sigaction Signal-catching function.
41440 The storage occupied by sa_handler and sa_sigaction may overlap,
and a conforming application
41441 shall not use both simultaneously.
